Subject: [PATCH 09/15] drm/i915: Generalize cursor size checks a bit
Date: Mon, 27 Mar 2017 21:55:40 +0300	[thread overview]
Message-ID: <20170327185546.2977-10-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20170327185546.2977-1-ville.syrjala@linux.intel.com>

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

We have the maximum cursor dimensions stored in the mode_config, so
let's just consult that information instead of hardcoding the same
information in multiple places.

We still need to keep some per-platform checks as the limitations are
quite diverse.
