Yes, please do. The Fixes tag is

   Fixes: ddddedaa0db9 ("drm/shmem-helper: Fix locking for 
drm_gem_shmem_get_pages_sgt()")

This commit is in drm-misc-next-fixes. But the branch is closed already 
as we're in the middle of the merge window. I think it's best to merge 
the fix through drm-misc-fixes after the -rc1 hs been tagged.

Best regards
Thomas
