This needs the same fix for the subject prefix that I mentioned for your
other patch, otherwise:

Reviewed-by: Thierry Reding 

Perhaps a good idea would be to send all of these patches with the
subject prefix fixed up as a second version and threaded in a series.
That makes it easier for people to pick them up (assuming Dave will take
them directly).

[PATCH 1/1] GPU-DRM-MSM: Deletion of unnecessary checks before two function calls

[SF Markus Elfring]

From: Markus Elfring

The functions framebuffer_release() and vunmap() perform also input
parameter validation. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
