Subject: Bluetooth: Use devm_kzalloc in btwilink.c file
X-Git-Tag: v3.7-rc1~70^2~42^2~37^2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4f8d81584964730b08753da34f1e3fb7981cf742;p=platform%2Fkernel%2Flinux-stable.git

Bluetooth: Use devm_kzalloc in btwilink.c file

devm_kzalloc() eliminates the need to free memory explicitly
thereby saving some cleanup code.
