From abf1aae8259e7f24dc88ebba4a5df1f8fd72f7c8 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 21 Mar 2019 15:24:46 +0200 Subject: drm/i915: Clean up EDID downclock mode lookup MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rename intel_find_panel_downclock() to intel_panel_edid_downclock_mode() to make it clear it's looking for the downclock mode in the EDID. And while at it polish the implementation a bit as well.
