Subject: [PATCH 1/1] ath9k: spin_lock_bh is not required within tasklet context.
Date: Thu, 23 Dec 2010 21:06:57 +0530 [thread overview]
Message-ID: <1293118617-1687-1-git-send-email-senthilkumar@atheros.com> (raw)
Disabling BH is not required while running from a tasklet context
and so replace spin_lock_bh with just spin_lock.
