[PATCH] drm/core: Remove drm_dev_unref() and it's uses

From: Vaishali Thakkar
Date: Thu Apr 26 2018 - 06:32:13 EST

It's been a while since we introduced drm_dev{get/put} functions
to replace reference/unreference in drm subsystem for the
consistency purpose. So, with this patch, let's just replace
all current use cases of drm_dev_unref() with drm_dev_put and remove
the function itself.

Coccinelle was used for mass-patching.
