Subject: qlogic: Deletion of unnecessary checks before two function calls
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=7061b2bdd620e4dda449d4d4db69de57751ab289;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

qlogic: Deletion of unnecessary checks before two function calls

The functions kfree() and vfree() perform also input parameter validation.
Thus the test around their calls is not needed.

This issue was detected by using the Coccinelle software.
