[PATCH 5/7] drm: Replace drm_gem_object_unreference_unlocked with put function
Thomas Zimmermann
tdz at users.sourceforge.net
Sat Jun 9 13:18:03 UTC 2018
This patch unifies the naming of DRM functions for reference counting
of struct drm_gem_object. The resulting code is more aligned with the
rest of the Linux kernel interfaces.
The patch also deletes the old function and removes it from the
Coccinelle script.
