Subject: drm/bochs: Remove unecessary NULL check in gem_free
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e0c6a73fb191daad6d4ea808a89c6e22ac1b2733;p=linux-beck.git

drm/bochs: Remove unecessary NULL check in gem_free

The ->gem_free_object never gets called with a NULL pointer, the check
is redundant. Also checking after the upcast allows compilers to elide
it anyway.

Noticed while chasing coverity reports, somehow this one here was not
flagged.
