Releasing the scan_pending lock in mwifiex_check_next_scan_command
introduces a short window where pending scan commands can be removed
or added before removing them all in mwifiex_cancel_pending_scan_cmd.
I think this is safe, since the worst thing to happen is that a
pending scan cmd is removed by the command handler. Adding new scan
commands is not possible while one is pending, see scan_processing flag.
Since all commands are removed from the queue anyway, we don't care if
some commands are removed by a different code path earlier, the final
state remains the same.
I assume, that the critical section needed for the check has been
extended over clearing the pending scan queue out of convenience. The
lock was already held and releasing it and grab it again was just
more work. It doesn't seem to be necessary because of concurrency.

switch. This makes the normal _probe() name available for a standard
Linux device driver probe function.

====================
To synchronize with Kalle, here's just a big change that affects
all drivers - removing the duplicated enum ieee80211_band and
replacing it by enum nl80211_band. On top of that, just a small
documentation update.

tipc: remove remnants of old broadcast code

====================
net: mediatek: make the driver pass stress tests
While testing the driver we managed to get the TX path to stall and fail
to recover. When dual MAC support was added to the driver, the whole queue
stop/wake code was not properly adapted. There was also a regression in the
locking of the xmit function. The fact that watchdog_timeo was not set and
that the tx_timeout code failed to properly reset the dma, irq and queue
just made the mess complete.
This series make the driver pass stress testing. With this series applied
the testbed has been running for several days and still has not locked up.
We have a second setup that has a small hack patch applied to randomly stop
irqs and/or one of the queues and successfully manages to recover from these
simulated tx stalls.

net: mediatek: do not set the QID field in the TX DMA descriptors
The QID field gets set to the mac id. This made the DMA linked list queue
the traffic of each MAC on a different internal queue. However during long
term testing we found that this will cause traffic stalls as the multi
queue setup requires a more complete initialisation which is not part of
the upstream driver yet.
This patch removes the code setting the QID field, resulting in all
traffic ending up in queue 0 which works without any special setup.
