Subject: drm/vmwgfx: Deletion of an unnecessary check before the function call "vfree"
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a3a1a6674f7fd6c0f7e673c4fc1b1aea3d8fce53;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/vmwgfx: Deletion of an unnecessary check before the function call "vfree"

The vfree() function performes also input parameter validation. Thus the test
around the call is not needed.

This issue was detected by using the Coccinelle software.
