From: Rob Clark Date: Wed, 2 Nov 2016 13:51:06 +0000 (-0400) Subject: drm/msm/mdp5: clip img size to src size X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=394da4b8f37e6ceceed68821957de5fc9e22b69b;p=linux.git drm/msm/mdp5: clip img size to src size If fb dimensions are larger than what can be scanned out, but the src dimensions are not, the hw can still handle this. So clip.
