Subject: [PATCH 08/15] drm/i915/dp: Use int for DSC slice count variables
Date: Wed, 14 Jan 2026 18:22:25 +0200 [thread overview]
Message-ID: <20260114162232.92731-9-imre.deak@intel.com> (raw)
In-Reply-To: <20260114162232.92731-1-imre.deak@intel.com>
There is no reason to use the more specific u8 type for slice count
variables, use the more generic int type instead.
