Subject: drm/msm: Delete an unnecessary check before drm_gem_object_unreference()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0a677125d0ff726ed3d75ab311cf54674bf512bc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/msm: Delete an unnecessary check before drm_gem_object_unreference()

The drm_gem_object_unreference() 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.
