[PATCH 5/8] drm: mali-dp: Fix destination size handling when rotating

From: Liviu Dudau
Date: Tue Jan 17 2017 - 11:39:46 EST


From: Brian Starkey <brian.starkey@xxxxxxx>

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.

Fixes: ad49f8602fe8 ("drm/arm: Add support for Mali Display Processors")
