From b75efff5f542fe31a1a894ed72f57f8e3139d22d Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Sat, 15 Aug 2020 14:54:03 +0200 Subject: [PATCH] drm/panel: leadtek: Use dev_ based logging MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Standardize on the dev_ based logging and drop the include of drm_print.h. Fix a few cases where "x@" was used when printing the mode.
