Subject: [IPV4]: Remove dead code from ip_output.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0d0d2bba97cb091218ea0bcb3d8debcc7bf48397;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[IPV4]: Remove dead code from ip_output.c

skb_prev is assigned from skb, which cannot be NULL. This patch removes the
unnecessary NULL check.
