[PATCH v3 19/28] drm/radeon: switch to drm_*_get(), drm_*_put() helpers

From: Cihangir Akturk
Date: Fri Aug 11 2017 - 08:35:00 EST


Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.
