Subject: mISDN: Deletion of unnecessary checks before the function call "vfree"
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=3819ffdff70da4c0d3bab0f8becabfc6936a230c;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

mISDN: Deletion of unnecessary checks before the function call "vfree"

The vfree() function performs also input parameter validation. Thus the test
around the call is not needed.

This issue was detected by using the Coccinelle software.
