Also this one should be replaced by the output of dim cite <sha1>, but
I think dim doesn't check for these.

* [PATCH] drm/vmwgfx: Make sure we unpin no longer needed buffers

We were not correctly unpinning no longer needed buffers. In particular
vmw_buffer_object, which is internally often pinned on creation wasn't
unpinned on destruction and none of the internal MOB buffers were
unpinned before being put back. Technically this existed for a
long time but 57fcd550eb15bce14a7154736379dfd4ed60ae81 introduced
a WARN_ON which was filling up the kernel logs rather quickly.
Quite frankly internal usage of vmw_buffer_object and in general
pinning needs to be refactored in vmwgfx but for now this makes
it work.
