Subject: [PATCH v2 4/6] drm/i915: Use & instead if == to check for rotations
Date: Fri, 21 Oct 2016 22:22:46 +0300	[thread overview]
Message-ID: <1477077768-4274-5-git-send-email-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <1477077768-4274-1-git-send-email-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Using == to check for 180 degree rotation only works as long as the
reflection bits aren't set. That will change soon enough for CHV, so
let's stop doing things the wrong way.

v2: Drop the BIT()
