[PATCH 6/7] drm: Replace drm_dev_unref with drm_dev_put

Thomas Zimmermann tdz at users.sourceforge.net
Sat Jun 9 13:18:04 UTC 2018


This patch unifies the naming of DRM functions for reference counting
of struct drm_device. 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.
