Julia Lawall 1aea7aee80 thermal: broadcom: constify thermal_zone_of_device_ops structure
The thermal_zone_of_device_ops structure can be const as it is only
passed as the last argument of thermal_zone_of_sensor_register
and the corresponding parameter is declared as const.

Done with the help of Coccinelle.

Jouni Malinen 312ca38ddd cfg80211: Fix busy loop regression in ieee80211_ie_split_ric()
This function was modified to support the information element extension
case (WLAN_EID_EXTENSION) in a manner that would result in an infinite
loop when going through set of IEs that include WLAN_EID_RIC_DATA and
contain an IE that is in the after_ric array. The only place where this
can currently happen is in mac80211 ieee80211_send_assoc() where
ieee80211_ie_split_ric() is called with after_ric[].

This can be triggered by valid data from user space nl80211
association/connect request (i.e., requiring GENL_UNS_ADMIN_PERM). The
only known application having an option to include WLAN_EID_RIC_DATA in
these requests is wpa_supplicant and it had a bug that prevented this
specific contents from being used (and because of that, not triggering
this kernel bug in an automated test case ap_ft_ric) and now that this
bug is fixed, it has a workaround to avoid this kernel issue.
WLAN_EID_RIC_DATA is currently used only for testing purposes, so this
does not cause significant harm for production use cases.

Emmanuel Grumbach 990d71846a mac80211: ignore NullFunc frames in the duplicate detection
NullFunc packets should never be duplicate just like
QoS-NullFunc packets.

We saw a client that enters / exits power save with
NullFunc frames (and not with QoS-NullFunc) despite the
fact that the association supports HT.
This specific client also re-uses a non-zero sequence number
for different NullFunc frames.
At some point, the client had to send a retransmission of
the NullFunc frame and we dropped it, leading to a
misalignment in the power save state.
Fix this by never consider a NullFunc frame as duplicate,
just like we do for QoS NullFunc frames.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=201449

Felix Fietkau 9ec1190d06 mac80211: fix reordering of buffered broadcast packets
If the buffered broadcast queue contains packets, letting new packets bypass
that queue can lead to heavy reordering, since the driver is probably throttling
transmission of buffered multicast packets after beacons.

Keep buffering packets until the buffer has been cleared (and no client
is in powersave mode).

Peter Shih 100bc3e2be tty: serial: 8250_mtk: always resume the device in probe.
serial8250_register_8250_port calls uart_config_port, which calls
config_port on the port before it tries to power on the port. So we need
the port to be on before calling serial8250_register_8250_port. Change
the code to always do a runtime resume in probe before registering port,
and always do a runtime suspend in remove.

This basically reverts the change in commit 68e5fc4a25 ("tty: serial:
8250_mtk: use pm_runtime callbacks for enabling"), but still use
pm_runtime callbacks.

Johan Hovold f51ccf4621 USB: serial: console: fix reported terminal settings
The USB-serial console implementation has never reported the actual
terminal settings used. Despite storing the corresponding cflags in its
struct console, these were never honoured on later tty open() where the
tty termios would be left initialised to the driver defaults.

Unlike the serial console implementation, the USB-serial code calls
subdriver open() already at console setup. While calling set_termios()
and write() before open() looks like it could work for some USB-serial
drivers, others definitely do not expect this, so modelling this after
serial core is going to be intrusive, if at all possible.

Instead, use a (renamed) tty helper to save the termios data used at
console setup so that the tty termios reflects the actual terminal
settings after a subsequent tty open().

Note that the calls to tty_init_termios() (tty_driver_install()) and
tty_save_termios() are serialised using the disconnect mutex.

This specifically fixes a regression that was triggered by a recent
change adding software flow control to the pl2303 driver: a getty trying
to disable flow control while leaving the baud rate unchanged would now
also set the baud rate to the driver default (prior to the flow-control
change this had been a noop).

Enric Balletbo i Serra 48a2ca0ee3 Revert "mfd: cros_ec: Use devm_kzalloc for private data"
This reverts commit 3aa2177e47.

That commit triggered a new WARN when unloading the module (see at the
end of the commit message). When a class_dev is embedded in a structure
then that class_dev is the thing that controls the lifetime of that
structure, for that reason device managed allocations can't be used here.
See Documentation/kobject.txt.

Revert the above patch, so the struct is allocated using kzalloc and we
have a release function for it that frees the allocated memory, otherwise
it is broken.

 ------------[ cut here ]------------
 Device 'cros_ec' does not have a release() function, it is broken and must be fixed.

Harry Pan 2f2dde6ba8 usb: quirk: add no-LPM quirk on SanDisk Ultra Flair device
Some lower volume SanDisk Ultra Flair in 16GB, which the VID:PID is
in 0781:5591, will aggressively request LPM of U1/U2 during runtime,
when using this thumb drive as the OS installation key we found the
device will generate failure during U1 exit path making it dropped
from the USB bus, this causes a corrupted installation in system at
the end.

i.e.,
[  166.918296] hub 2-0:1.0: state 7 ports 7 chg 0000 evt 0004
[  166.918327] usb usb2-port2: link state change

[  167.276058] usb 2-2: unregistering device
[  167.276060] usb 2-2: unregistering interface 2-2:1.0
[  167.276170] xhci_hcd 0000:00:15.0: shutdown urb ffffa3c7cc695cc0 ep1in-bulk

...

Analyzed the USB trace in the link layer we realized it is because
of the 6-ms timer of tRecoveryConfigurationTimeout which documented
on the USB 3.2 Revision 1.0, the section 7.5.10.4.2 of "Exit from
Recovery.Configuration"; device initiates U1 exit -> Recovery.Active
-> Recovery.Configuration, then the host timer timeout makes the link
transits to eSS.Inactive -> Rx.Detect follows by a Warm Reset.

Interestingly, the other higher volume of SanDisk Ultra Flair sharing
the same VID:PID, such as 64GB, would not request LPM during runtime,
it sticks at U0 always, thus disabling LPM does not affect those thumb
drives at all.

The same odd occures in SanDisk Ultra Fit 16GB, VID:PID in 0781:5583.

The problem is caused by use of a static array to store
environment-string pointers.  When the routine is called by multiple
threads concurrently, the pointers from one thread can overwrite those
from another.

The solution is to use an ordinary automatic array instead of a static
array.

correct. So used the correct reference used to store roc related
information during the scan.
