[PATCH v7 0/2] DRM GEM fixes

[Dmitry Osipenko <dmitry.osipenko@collabora.com>]

This patchset fixes two problems in the common GEM code. First fixed problem
is the bogus lockdep splat that complicates debugging of DRM drivers. Second
problem is the inconsistency in behaviour and improper handling of mapping
the imported GEMs by some drivers, to fix it we will prohibit to map the
imported GEMs like majority of drivers already do.

Changelog:

v7: - Factored out GEM patches from [1] since I'll be working on the
      dma-buf locking in a separate patchsets now.

[1] https://lore.kernel.org/all/20220526235040.678984-1-dmitry.osipenko@collabora.com/

    - Improved commit message and added fixes tag to the "Properly annotate
      WW context" patch.

    - Replaced "Move mapping of imported dma-bufs to drm_gem_mmap_obj()"
      patch with "Don't map imported GEMs", like was suggested by
      Thomas Hellström.

    - Added r-b and suggested-by from Thomas Hellström.
