Subject: [PATCH 03/11] drm/i915: Use fixed_16_16 wrapper for division operation
Date: Mon,  8 May 2017 17:18:54 +0530	[thread overview]
Message-ID: <20170508114902.18965-4-mahesh1.kumar@intel.com> (raw)
In-Reply-To: <20170508114902.18965-1-mahesh1.kumar@intel.com>

Don't use fixed_16_16 structure members directly, instead use wrapper to
perform fixed_16_16 division operation.
