Subject: drbd: Deletion of an unnecessary check before the function call "lc_destroy"
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d01efceeea99d91022e14aa4169857b1256bcba5;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

drbd: Deletion of an unnecessary check before the function call "lc_destroy"

The lc_destroy() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
