ath10k: Fix mutex unlock balance
...
ath10k_debug_read_target_stats is properly
protected by data_lock (spinlock). Remove
the unwanted mutex_unlock(&ar->conf_mutex)
[ BUG: bad unlock balance detected! ]
-------------------------------------
kworker/u4:0/12459 is trying to release lock
(&ar->conf_mutex) at:
[<c16a170d>] mutex_unlock+0xd/0x10
but there are no more locks to release!

ath10k: create debugfs interface to trigger fw crash
...
This can be useful for testing. To perform a
forced firmware crash write 'crash' to
'simulate_fw_crash' debugfs file. E.g.
echo crash > /sys/kernel/debug/ieee80211/phy1/ath10k/simulate_fw_crash

ath10k: skip fw stats debugfs interface if device is down
...
If the device is not running then there may be no
FW at all to send the query to. If the FW is
already there it might still trigger a crash if
the command is sent before the device is fully
initialized.

ath10k: mac80211 driver for Qualcomm Atheros 802.11ac CQA98xx devices
...
Here's a new mac80211 driver for Qualcomm Atheros 802.11ac QCA98xx devices.
A major difference from ath9k is that there's now a firmware and
that's why we had to implement a new driver.
The wiki page for the driver is:
http://wireless.kernel.org/en/users/Drivers/ath10k
The driver has had many authors, they are listed here alphabetically:
