[Intel-gfx] [PATCH] drm/i915: Downgrade pipe state mismatches to DRM_DEBUG_KMS

[Adam Jackson]

This is, by far, the most common kernel retrace in i915 I'm seeing:

https://retrace.fedoraproject.org/faf/problems/1346879/

There's not enough information in the backtrace to know if something
actually went wrong or if this is just an assertion failure, so it's
pretty useless.  Downgrade this to DRM_DEBUG_KMS so we can still see it
if we want it.
