For some reason I'm not receiving buildbot emails anymore, but I noticed
via the kbuild-all archives that this patch has a warning:

   drivers/net/wireless/ath/ath10k/mac.c: In function 'ath10k_drain_tx':
>> drivers/net/wireless/ath/ath10k/mac.c:2442:2: error: implicit
declaration of function 'lockdep_is_held'
