If an error occurs after a successful 'clk_prepare_enable()' call, it must
be undone by a corresponding 'clk_disable_unprepare()' call.
This call is already present in the remove function.
Add this call in the error handling path and reorder the code so that the
'clk_prepare_enable()' call happens later in the function.
The goal is to have as much managed resources functions as possible

When a remote usb device is attached to the local Virtual USB
Host Controller Root Hub port, the bound device driver may send
a port reset command.
vhci_hcd accepts port resets only when the device doesn't have
port address assigned to it. When reset happens device is in
assigned/used state and vhci_hcd rejects it leaving the port in
a stuck state.
This problem was found when a blue-tooth or xbox wireless dongle
was passed through using usbip.
A few drivers reset the port during probe including mt76 driver
specific to this bug report. Fix the problem with a change to
honor reset requests when device is in used state (VDEV_ST_USED).

This reverts commit 5d5323a6f3.
That commit effectively disabled Intel host initiated U1/U2 lpm for devices
with periodic endpoints.
Before that commit we disabled host initiated U1/U2 lpm if the exit latency
was larger than any periodic endpoint service interval, this is according
to xhci spec xhci 1.1 specification section 4.23.5.2
After that commit we incorrectly checked that service interval was smaller
than U1/U2 inactivity timeout. This is not relevant, and can't happen for
Intel hosts as previously set U1/U2 timeout = 105% * service interval.
Patch claimed it solved cases where devices can't be enumerated because of
bandwidth issues. This might be true but it's a side effect of accidentally
turning off lpm.
exit latency calculations have been revised since then

Only TDs with status TD_CLEARING_CACHE will be given back after
cache is cleared with a set TR deq command.
xhci_invalidate_cached_td() failed to set the TD_CLEARING_CACHE status
for some cancelled TDs as it assumed an endpoint only needs to clear the
TD it stopped on.
This isn't always true. For example with streams enabled an endpoint may
have several stream rings, each stopping on a different TDs.
Note that if an endpoint has several stream rings, the current code
will still only clear the cache of the stream pointed to by the last
cancelled TD in the cancel list.
This patch only focus on making sure all canceled TDs are given back,
avoiding hung task after device removal.
Another fix to solve clearing the caches of all stream rings with
cancelled TDs is needed, but not as urgent.
This issue was simultanously discovered and debugged by
by Tao Wang, with a slightly different fix proposal.

f_hid provides the OUT Endpoint as only way for receiving reports
from the host. SETUP/SET_REPORT method is not supported, and this causes
a number of compatibility problems with various host drivers, especially
in the case of keyboard emulation using f_hid.
- Some hosts do not support the OUT Endpoint and ignore it,
so it becomes impossible for the gadget to receive a report
from the host. In the case of a keyboard, the gadget loses
the ability to receive the status of the LEDs.
- Some BIOSes/UEFIs can't work with HID devices with the OUT Endpoint
at all. This may be due to their bugs or incomplete implementation
of the HID standard.
For example, absolutely all Apple UEFIs can't handle the OUT Endpoint
if it goes after IN Endpoint in the descriptor and require the reverse
order (OUT, IN) which is a violation of the standard.
Other hosts either do not initialize gadgets with a descriptor
containing the OUT Endpoint completely (like some HP and DELL BIOSes
and embedded firmwares like on KVM switches), or initialize them,
but will not poll the IN Endpoint.
This patch adds configfs option no_out_endpoint=1 to disable
the OUT Endpoint and allows f_hid to receive reports from the host
via SETUP/SET_REPORT.
Previously, there was such a feature in f_hid, but it was replaced
by the OUT Endpoint [1] in the commit 99c5150058 ("usb: gadget: hidg:
register OUT INT endpoint for SET_REPORT"). So this patch actually
returns the removed functionality while making it optional.
For backward compatibility reasons, the OUT Endpoint mode remains
the default behaviour.
- The OUT Endpoint mode provides the report queue and reduces
USB overhead (eliminating SETUP routine) on transmitting a report
from the host.
- If the SETUP/SET_REPORT mode is used, there is no report queue,
so the userspace will only read last report. For classic HID devices
like keyboards this is not a problem, since it's intended to transmit
the status of the LEDs and only the last report is important.
This mode provides better compatibility with strange and buggy
host drivers.
Both modes passed USBCV tests. Checking with the USB protocol analyzer
also confirmed that everything is working as it should and the new mode
ensures operability in all of the described cases.

For now, I'm operating under the assumption that we'll fully remove

We currently check for ret != 0 to indicate error, but '1' is a valid
return and just indicates that the allocation succeeded with a wrap.
Correct the check to be for < 0, like it was before the xarray
conversion.
