From 45dea7b0c60738cc4920fa0d39b8d44398436659 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 17 Mar 2017 23:17:59 +0200 Subject: [PATCH] drm/i915: Extract ivb_sprite_ctl() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Pull the code to calculate the IVB-BDW sprite control register value into a separate function. Allows us to pre-compute it in the future.
