[v4,15/15] drm/shmem-helper: Remove drm_gem_shmem_purge()

Commit Message

Dmitry Osipenko April 17, 2022, 10:37 p.m. UTC

The drm_gem_shmem_purge() was added back in 2019 and never had a user
since then. GEM's purging is now managed by the generic shrinker and
only the "locked" variant of the function is wanted. Remove the obsoleted
function.
