Subject: [media] s5k6aa: Use devm_kzalloc function
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=dc9c94cd339dc74b73ca7ef0943ea610d02f8e3e;p=openwrt%2Fstaging%2Fblogic.git

[media] s5k6aa: Use devm_kzalloc function

devm_kzalloc() eliminates the need to free explicitly thereby
making the code a bit simpler.
