From: Dmitry Baryshkov Date: Tue, 3 Sep 2024 03:22:58 +0000 (+0300) Subject: drm/msm/dpu: sync mode_config limits to the FB limits in dpu_plane.c X-Git-Tag: v6.13-rc1~122^2~11^2~8 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2261751d5f2233a7a5d4791d6d13a0271e838ca5;p=thirdparty%2Fkernel%2Flinux.git drm/msm/dpu: sync mode_config limits to the FB limits in dpu_plane.c Lift mode_config limits set by the DPU driver to the actual FB limits as handled by the dpu_plane.c. Move 2*max_lm_width check where it belongs, to the drm_crtc_helper_funcs::mode_valid() callback.
