File N_amdgpu-present-Check-tiling-for-newer-versions-too.patch of Package xf86-video-amdgpu

From: Takashi Iwai <tiwai@suse.de>
Subject: present: Check tiling for newer versions, too
Patch-mainline: Never, temporary workaround
References: bsc#1169222

This is essentially a partial revert of the commit a2b32e72fdaf
  present: Don't check tiling parameters with DC & DRM minor version >= 31

that caused a crash when DPMS is changed while an external HDMI
monitor is connected on the laptop.

Note that it's a temporary workaround until the actual cause gets
fixed in the kernel DRM side.
