X-Git-Tag: v5.15~7972^2~3^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=57078338b2e4c07fb76bef23369cae0acfb1f7bc;p=platform%2Fkernel%2Flinux-starfive.git drm: fix drm_drv_uses_atomic_modeset on non modesetting drivers. vgem seems to oops on the intel CI due to the vgem debugfs init hitting this path now. Check if we have mode_config funcs before checking one.
