This is a note to let you know that I've just added the patch titled drm: mali-dp: Fix destination size handling when rotating to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: drm-mali-dp-fix-destination-size-handling-when-rotating.patch and it can be found in the queue-4.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From foo@baz Thu Oct 5 10:28:31 CEST 2017 From: Brian Starkey <brian.starkey@xxxxxxx> Date: Wed, 7 Dec 2016 13:17:21 +0000 Subject: drm: mali-dp: Fix destination size handling when rotating From: Brian Starkey <brian.starkey@xxxxxxx> [ Upstream commit edabb3c4cd2d035bc93a3d67b25a304ea6217301 ] The destination rectangle provided by userspace in the CRTC_X/Y/W/H properties is already expressed as the dimensions after rotation. This means we shouldn't swap the width and height ourselves when a 90/270 degree rotation is requested, so remove the code doing the swap.
