Subject: net-ipv6: Delete an unnecessary check before the function call "free_percpu"
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=87775312a86bcf213e3b21f6f7c79e2e00d96f7b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

net-ipv6: Delete an unnecessary check before the function call "free_percpu"

The free_percpu() 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.
