From 09951aaa7229b253b0e00979d6c6d17b20e16fe4 Mon Sep 17 00:00:00 2001 From: Sean Paul Date: Mon, 17 Jun 2019 16:12:53 -0400 Subject: drm/msm/dsi: Don't store dsi host mode_flags in msm_dsi It's a bit dangerous to store the flags in msm_dsi since there's no way to tell when they're populated. Fortunately the only place that uses them is the same place that fills them. So just use a local variable and delete the struct member.
