Subject: ath9k: spin_lock_bh is not required within tasklet context.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=52671e43dbfb0e0dfa5fab604cb3984bd1d777a6;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

ath9k: spin_lock_bh is not required within tasklet context.

Disabling BH is not required while running from a tasklet context
and so replace spin_lock_bh with just spin_lock.
