Subject: cipso: remove an unneeded NULL check in cipso_v4_doi_add()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=56755924100261b8e52dca68ca53ece54b6f64ad;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

cipso: remove an unneeded NULL check in cipso_v4_doi_add()

We dereference doi_def on the line before the NULL check.  It has
been this way since 2008.  I checked all the callers and doi_def is
always non-NULL here.
