From ee216bd1aa5f124003f33d5d15b979c594c2775c Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Sat, 22 Jan 2022 00:06:13 +0300 Subject: [PATCH] drm/msm/dpu: drop unused lm_max_width from RM No code uses lm_max_width from resource manager, so drop it. Instead of calculating the lm_max_width, code can use max_mixer_width field from the hw catalog.
