X-Git-Tag: 2.1b_release~5947^2~14^2~3^2~39 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=52671e43dbfb0e0dfa5fab604cb3984bd1d777a6;p=platform%2Fkernel%2Fkernel-mfld-blackbay.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. Signed-off-by: Senthil Balasubramanian Signed-off-by: John W.
