#     Merge tag 'drm-fixes-2022-05-14' of git://anongit.freedesktop.org/drm/drm
#     
#     Pull more drm fixes from Dave Airlie:
#      "Turns out I was right, some fixes hadn't made it to me yet. The vmwgfx
#       ones also popped up later, but all seem like bad enough things to fix.
#       The dma-buf, vc4 and nouveau ones are all pretty small.
#     
#       The fbdev fixes are a bit more complicated: a fix to cleanup fbdev
#       devices properly, uncovered some use-after-free bugs in existing
#       drivers. Then the fix for those bugs wasn't correct. This reverts that
#       fix, and puts the proper fixes in place in the drivers to avoid the
#       use-after-frees.
#     
#       This has had a fair number of eyes on it at this stage, and I'm
#       confident enough that it puts things in the right place, and is less
#       dangerous than reverting our way out of the initial change at this
#       stage.
#     
#       fbdev:
#        - revert NULL deref fix that turned into a use-after-free
#        - prevent use-after-free in fbdev
#        - efifb/simplefb/vesafb: fix cleanup paths to avoid use-after-frees
#     
#       dma-buf:
#        - fix panic in stats setup
#     
#       vc4:
#        - fix hdmi build
#     
#       nouveau:
#        - tegra iommu present fix
#        - fix leak in backlight name
#     
#       vmwgfx:
#        - Black screen due to fences using FIFO checks on SVGA3
#        - Random black screens on boot due to uninitialized drm_mode_fb_cmd2
#        - Hangs on SVGA3 due to command buffers being used with gbobjects"
