From 13f2cb9a280054c9c95c694a8837fd0828b03853 Mon Sep 17 00:00:00 2001 From: Dhinakaran Pandiyan Date: Sat, 21 Dec 2019 14:05:36 +0200 Subject: [PATCH] drm/i915: Extract framebufer CCS offset checks into a function MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit intel_fill_fb_info() has grown quite large and wrapping the offset checks into a separate function makes the loop a bit easier to follow. v2: Skip the check for non-CCS planes.
