From: Emil Velikov @ 2020-05-15  9:50 UTC (permalink / raw)
  To: dri-devel; +Cc: emil.l.velikov, Rob Clark, Sean Paul, linux-arm-msm

From: Emil Velikov <emil.velikov@collabora.com>

Vast majority of DRM (core and drivers) are struct_mutex free.

As such we have only a handful of cases where the locked helper should
be used. Make that stand out a little bit better.

Done via the following script:

__from=drm_gem_object_put
__to=drm_gem_object_put_locked

for __file in $(git grep --name-only --word-regexp $__from); do
  sed -i  "s/\<$__from\>/$__to/g" $__file;
done

_put_unlocked() is going away. I think you have to update this line in
patch 12. (?)

NIT: The subject is wrong: s/drm_object_put/drm_gem_object_put/

Otherwise with that fixes LTGM:
