[PATCH 36/36] drm/gem: remove _unlocked suffix in drm_object_put_unlocked
Emil Velikov
emil.l.velikov at gmail.com
Thu May 7 15:08:22 UTC 2020
From: Emil Velikov <emil.velikov at collabora.com>
Spelling out _unlocked for each and every driver is a annoying.
Especially if we consider how many drivers, do not know (or need to)
about the horror stories involving struct_mutex.
Just drop the suffix. It makes the API cleaner.
Done via the following script:
__from=drm_gem_object_put_unlocked
__to=drm_gem_object_put
for __file in $(git grep --name-only $__from); do
sed -i "s/$__from/$__to/g" $__file;
done
With this patch, the _unlocked define is no longer needed - remove it.
