[PATCH v2] drm/i915: Replace *_reference/unreference() or *_ref/unref with _get/put()

Harsha Sharma
2017-09-29T04:30:19Z

Replace instances of drm_framebuffer_reference/unreference() with
*_get/put() suffixes and drm_dev_unref with *_put() suffix
because get/put is shorter and consistent with the
kernel use of *_get/put suffixes.
Done with following coccinelle semantic patch
