Re: [PATCH 2/2] ath10k: detect conf_mutex held ath10k_drain_tx() calls

Shuah Khan [off-list ref] writes:

ath10k_drain_tx() must not be called with conf_mutex held as workers can
use that also. Add call to lockdep_assert_not_held() on conf_mutex to
detect if conf_mutex is held by the caller.

The idea for this patch stemmed from coming across the comment block
above the ath10k_drain_tx() while reviewing the conf_mutex holds during
to debug the conf_mutex lock assert in ath10k_debug_fw_stats_request().

Adding detection to assert on conf_mutex hold will help detect incorrect
usages that could lead to locking problems when async worker routines try
to call this routine.

This can go via the same tree as patch 1:

Acked-by: Kalle Valo <redacted>

But I can also take this to my ath tree, once patch 1 has reached it.
Just let me know what is preferred.
