The way to load the HQVDP firmware has been updated.
HQVDP firmware is now loaded the first time an HQVDP plane is used and
no more when the HQVDP driver is bound.
This solves the dependency we had on the file system availability.
The first time the HQVDP plane is used, we are sure that file system is
available so request_firmware function will match.
CONFIG_FW_LOADER_USER_HELPER_FALLBACK is then no more mandatory.

arg is long int, so arg = (arg << 22) >> 22 makes the upper 22 bits of
arg equal to bit 9 (or bit 41). But we then mask away all but bits 0-9, so
this is entirely redundant.

The commit 53bdcf5f026c ("drm: sti: fix sub-components bind") moves
i2c adapter search and locking from .bind() to .probe(), however
proper error path in the modified .probe() is not implemented and
leftover of the related error path in .bind() remains. This change
fixes these issues.

Currently, cfg80211 rejects updates of AID and listen interval parameters
for existing entries. This information is known only at association stage
and as a result it's impossible to update entries that were added
unassociated.
Fix this by allowing updates of these properies for stations that the
driver (or mac80211) assigned unassociated state.
This then fixes mac80211's use of NL80211_FEATURE_FULL_AP_CLIENT_STATE.

As WMM is required for HT/VHT operation, treat bad WMM parameters
more gracefully by falling back to default parameters instead of
not using WMM assocation. This makes it possible to still use HT
or VHT, although potentially with reduced quality of service due
to unintended WMM parameters.

Disabling WMM has a huge impact these days. It implies that
HT and VHT will be disabled which means that the throughput
will be drammatically reduced.
Since the AIFSN is a transmission parameter, we can play a
bit and fix it up to make it compliant with the 802.11
specification which requires it to be at least 2.
Increasing it from 1 to 2 will slightly reduce the
likelyhood to get a transmission opportunity compared to
other clients that would accept to set AIFSN=1, but at
least it will allow HT and VHT which is a huge gain.

The previous patch changed mac80211 to always report an event
after a CQM RSSI reconfiguration. Document that as expected
behaviour in both the cfg80211 and mac80211 API.
Currently, iwlmvm already implements that behaviour; the other
drivers implementing CQM RSSI events may have to be changed.
This behaviour lets userspace know what the current state is
without relying on querying the data which is racy.

Scheduled scan has to be reconfigured only if wowlan wasn't
configured, since otherwise it should continue to run (with
the 'any' trigger) or be aborted.

some memory (from the previous request.)

If drv_start() fails during hw_restart, all the running
interfaces are being closed/stopped, which results in
drv_stop() being called, although the driver was never
started successfully.
This might cause drivers to perform operations on uninitialized
memory (as they assume it was initialized on drv_start)
Consider the local->started flag, and call the driver's stop()
op only if drv_start() succeeded before.
Move drv_start() and drv_stop() to driver-ops.c, as they are no
longer simple wrappers.

Requesting hw restart during suspend might result
in the restart work being executed after mac80211
and the hw are suspended.
Solve the race by simply scheduling the restart
work on a freezable workqueue.
Note that there can be some cases of reconfiguration
on resume (besides the hardware restart):
* wowlan is not configured -
All the interfaces removed were removed on suspend,
and drv_stop() was called. At this point the driver
shouldn't expect for hw_restart anyway, so we can
simply cancel it (on resume).
* wowlan is configured, drv_resume() == 1
There is no definitive expected behavior in this case,
as each driver might have different expectations (e.g.
setting some flags on suspend/restart vs. not handling
spurious recovery).
For now, simply let the hw_restart work run again after
resume, and hope the driver will handle it well (or at
least initiate another hw restart).
