From 52671e43dbfb0e0dfa5fab604cb3984bd1d777a6 Mon Sep 17 00:00:00 2001 From: Senthil Balasubramanian <senthilkumar@atheros.com> Date: Thu, 23 Dec 2010 21:06:57 +0530 Subject: [PATCH] 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.
