In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields.
Use struct_group() in struct cp2112_string_report around members report,
length, type, and string, so they can be referenced together. This will
allow memcpy() and sizeof() to more easily reason about sizes, improve
readability, and avoid future warnings about writing beyond the end of
report.
"pahole" shows no size nor member offset changes to struct
cp2112_string_report. "objdump -d" shows no meaningful object

The snprintf() limits are complicated and slightly wrong when it does:
max(0, HID_DEBUG_BUFSIZE - len - 1)
The "- 1" should not be there. It means we can't use the last
byte of the buffer. If we change the first snprintf() to scnprintf()
then we can remove the max().
At the start of the function the strlen(buf) is going always going to
be < HID_DEBUG_BUFSIZE so that is safe. If it were > HID_DEBUG_BUFSIZE
then that would result in a WARN().

This patch makes a small simplification to the code in
hid_submit_ctrl(). The test for maxpacket being > 0 is unnecessary,
because endpoint 0 always has a maxpacket value which is >= 8.
Furthermore, endpoint 0's maxpacket value is always a power of 2, so
instead of open-coding the round-to-next-multiple computation we can
call the optimized round_up() routine.

Syzbot found a warning caused by hid_submit_ctrl() submitting a
control request to transfer a 0-length input report:
usb 1-1: BOGUS control dir, pipe 80000280 doesn't match bRequestType a1
(The warning message is a little difficult to understand. It means
that the control request claims to be for an IN transfer but this
contradicts the USB spec, which requires 0-length control transfers
always to be in the OUT direction.)
Now, a zero-length report isn't good for anything and there's no
reason for a device to have one, but the fuzzer likes to pick out
these weird edge cases. In the future, perhaps we will decide to
reject 0-length reports at probe time. For now, the simplest approach
for avoiding these warnings is to pretend that the report actually has
length 1.

[patch description by Alan Stern]
Commit 7652dd2c5c ("USB: core: Check buffer length matches wLength
for control transfers") causes control URB submissions to fail if the
transfer_buffer_length value disagrees with the setup packet's wLength
valuel. Unfortunately, it turns out that the usbhid can trigger this
failure mode when it submits a control request for an input report: It
pads the transfer buffer size to a multiple of the maxpacket value but
does not increase wLength correspondingly.
These failures have caused problems for people using an APS UPC, in
the form of a flood of log messages resembling:
hid-generic 0003:051D:0002.0002: control queue full
This patch fixes the problem by setting the wLength value equal to the
padded transfer_buffer_length value in hid_submit_ctrl(). As a nice
bonus, the code which stores the transfer_buffer_length value is now
shared between the two branches of an "if" statement, so it can be
de-duplicated.

Luckily, ./scripts/checkkconfigsymbols.py warns on non-existing configs:
HID_TMINIT
Referencing files: drivers/hid/Makefile, drivers/hid/hid-quirks.c
Following the discussion (see Link), CONFIG_HID_THRUSTMASTER is the

actually added as hid-thrustmaster.c.
So, clean up Makefile and adapt quirks to that refactoring.

This commit fixes a functional regression introduced by the commit 82f09a637d
("HID: ft260: improve error handling of ft260_hid_feature_report_get()")
when upon USB disconnect, the FTDI FT260 i2c device is still available within
the /dev folder.
In my company's product, where the host USB to FT260 USB connection is
hard-wired in the PCB, the issue is not reproducible. To reproduce it, I used
the VirtualBox Ubuntu 20.04 VM and the UMFT260EV1A development module for the
FTDI FT260 chip:
Plug the UMFT260EV1A module into a USB port and attach it to VM.
The VM shows 2 i2c devices under the /dev:
michael@michael-VirtualBox:~$ ls /dev/i2c-*
/dev/i2c-0 /dev/i2c-1
The i2c-0 is not related to the FTDI FT260:
michael@michael-VirtualBox:~$ cat /sys/bus/i2c/devices/i2c-0/name
SMBus PIIX4 adapter at 4100
The i2c-1 is created by hid-ft260.ko:
michael@michael-VirtualBox:~$ cat /sys/bus/i2c/devices/i2c-1/name
FT260 usb-i2c bridge on hidraw1
Now, detach the FTDI FT260 USB device from VM. We expect the /dev/i2c-1
to disappear, but it's still here:
michael@michael-VirtualBox:~$ ls /dev/i2c-*
/dev/i2c-0 /dev/i2c-1
And the kernel log shows:
[ +0.001202] usb 2-2: USB disconnect, device number 3
[ +0.000109] ft260 0003:0403:6030.0002: failed to retrieve system status
[ +0.000316] ft260 0003:0403:6030.0003: failed to retrieve system status
It happens because the commit 82f09a637d changed the ft260_get_system_config()
return logic. This caused the ft260_is_interface_enabled() to exit with error
upon the FT260 device USB disconnect, which in turn, aborted the ft260_remove()
before deleting the FT260 i2c device and cleaning its sysfs stuff.
This commit restores the FT260 USB removal functionality and improves the
ft260_is_interface_enabled() code to handle correctly all chip modes defined
by the device interface configuration pins DCNF0 and DCNF1.

Wacom touch devices have two types of touch switches: softkey touch
toggle and hardware touch switch. For softkey toggle, we assume
touch is on by default in the driver. However the hardware touch
switch is controlled by end users. We don't know if it's on or off
before getting the status event.
This patch sets touch off for devices with a hardware switch until we
get the status. This is a bit safer for users who leave the switch "off"
and don't want any accidental touches. The tradeoff is a slight delay
between device connection and touch becoming enabled for users who
leave the switch "on".

Commit 670e90924b ("HID: wacom: support named keys on older devices")
added support for sending named events from the soft buttons on the

touchscreen of the 24HDT and 27QHDT by default. The
`wacom_set_shared_values` function would normally enable touch by default
but because it checks the state of the non-shared `has_mute_touch_switch`
flag and `wacom_setup_touch_input_capabilities` sets the state of the
/shared/ version, touch ends up being disabled by default.
This patch sets the non-shared flag, letting `wacom_set_shared_values`
take care of copying the value over to the shared version and setting
the default touch state to "on".

Additionally some resource leaks were fixed that were caused by drivers
returning an error code in the expectation that the driver won't go
away.
With struct bus_type::remove returning void it's prevented that newly
implemented buses return an ignored error code and so don't anticipate
wrong expectations for driver authors.

The regulator for the touchscreen could be:
* A dedicated regulator just for the touchscreen.
* A regulator shared with something else in the system.
* An always-on regulator.
How we want the "reset" line to behave depends a bit on which of those
three cases we're in. Currently the code is written with the
assumption that it has a dedicated regulator, but that's not really
guaranteed to be the case.
The problem we run into is that if we leave the touchscreen powered on
(because someone else is requesting the regulator or it's an always-on
regulator) and we assert reset then we apparently burn an extra 67 mW
of power. That's not great.
Let's instead tie the control of the reset line to the true state of
the regulator as reported by regulator notifiers. If we have an
always-on regulator our notifier will never be called. If we have a
shared regulator then our notifier will be called when the touchscreen
is truly turned on or truly turned off.
Using notifiers like this nicely handles all the cases without
resorting to hacks like pretending that there is no "reset" GPIO if we
have an always-on regulator.
NOTE: if the regulator is on a shared line it's still possible that
things could be a little off. Specifically, this case is not handled
even after this patch:
1. Suspend goodix (send "sleep", goodix stops requesting regulator on)
2. Other regulator user turns off (regulator fully turns off).
3. Goodix driver gets notified and asserts reset.
4. Other regulator user turns on.
5. Goodix driver gets notified and deasserts reset.
6. Nobody resumes goodix.
With that set of steps we'll have reset deasserted but we will have
lost the results of the I2C_HID_PWR_SLEEP from the suspend path. That
means we might be in higher power than we could be even if the goodix
driver thinks things are suspended. Presumably, however, we're still
in better shape than if we were asserting "reset" the whole time. If
somehow the above situation is actually affecting someone and we want
to do better we can deal with it when we have a real use case.

The Magic Mouse, generations 1 and 2, doesn't have a physical scroll
wheel, instead, the REL_WHEEL and REL_HWHEEL events are emulated
when sliding a finger on the surface of the mouse.
However, the smooth movement of the finger is transformed into a step
based scroll on the screen, leading to a suboptimal user experience.
Emulate high-resolution scroll by sending REL_WHEEL_HI_RES and
REL_HWHEEL_HI_RES events so the scroll on the screen is closer to the
finger movement.

ISH IPC driver uses asynchronous workqueue to do resume now, but there is
a potential timing issue: when child devices resume before bus driver, it
will cause child devices resume failed and cannot be recovered until
reboot. The current implementation in this case do wait for IPC to resume
but fail to accommodate for a case when there is no ISH reboot and soft
resume is taking time. This issue is apparent on Tiger Lake platform with
5.11.13 kernel when doing suspend to idle then resume(s0ix) test. To
resolve this issue, we change ISHTP HID client to use asynchronous resume
callback too. In the asynchronous resume callback, it waits for the ISHTP
resume done event, and then notify ISHTP HID client link ready.

Getting a report (e.g. feature report) from a device requires us to send
a request indicating which report we want to retrieve and then waiting
for the corresponding response containing that report. We already
provide the response structure to the request call, but the request
isn't marked as a request that expects a response. Thus the request
returns before we receive the response and the response buffer indicates
a zero length response due to that.
This essentially means that the get-report calls are broken and will
always indicate that a report of length zero has been read.
Fix this by appropriately marking the request.

This commit fixes a freeze on insertion of a Guitar Hero Live PS3/WiiU
USB dongle. Indeed, with the current implementation, inserting one of
those USB dongles will lead to a hard freeze. I apologize for not
catching this earlier, it didn't occur on my old laptop.
While the issue was isolated to memory alloc/free, I could not figure
out why it causes a freeze. So this patch fixes this issue by
simplifying memory allocation and usage.
We remind that for the dongle to work properly, a control URB needs to
be sent periodically. We used to alloc/free the URB each time this URB
needed to be sent.
With this patch, the memory for the URB is allocated on the probe, reused
for as long as the dongle is plugged in, and freed once the dongle is
unplugged.
