[PATCH] drm/atomic: Remove WARN_ON for invalid plane configuration.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
