X-Git-Tag: v4.17-rc1~27^2~30^2~26 X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=fa5aaeecf524ecbcae9755ee3d34b7b8ba412583;p=uclinux-h8%2Flinux.git drm/atomic: Remove WARN_ON for invalid plane configuration. Userspace can set a FB_ID on a plane without setting CRTC_ID, which will fail with -EINVAL, but the kernel shouldn't warn about that. Same for !FB_ID and CRTC_ID being set.
