Subject: selinux: remove unnecessary pointer reassignment
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=83d4a806ae46397f606de7376b831524bd3a21e5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

selinux: remove unnecessary pointer reassignment

Commit f01e1af445fa ("selinux: don't pass in NULL avd to avc_has_perm_noaudit")
made this pointer reassignment unnecessary. Avd should continue to reference
the stack-based copy.
