From 53f1e0620b9b67f786b23c7e7fee96323bf2aa45 Mon Sep 17 00:00:00 2001 From: Souptick Joarder Date: Wed, 1 Aug 2018 01:37:05 +0530 Subject: [PATCH] drm/tegra: Convert drm_atomic_helper_suspend/resume() convert drm_atomic_helper_suspend/resume() to use drm_mode_config_helper_suspend/resume(). With this conversion, tegra_drm_fb_suspend() and tegra_drm_fb_resume() will not be used anymore. Both of these functions can be removed. Also, in tegra_drm struct's member state will not be used anymore. So this can be removed forever. Fixed one sparse warning.
