Subject: ath9k: Fix pending frame check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fc1314c75e0558c03cb434e2af2c257caa201e76;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ath9k: Fix pending frame check

Checking for the queue depth outside of
the TX queue lock is incorrect and in this
case, is not required since it is done inside
ath9k_has_pending_frames().
