Subject: drm/ast: use drm_modeset_lock_all
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=795f1426b484ddfc136e723a26bfd6a46c8ab085;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/ast: use drm_modeset_lock_all

Just a call to drm_helper_resume_force_mode, obviously wants full
locking for that.
