[PATCH 1/2] drm: do lower level device put on unplugged releases

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

When we release the file handle on a device that has been unplugged
it has already called the unregister path, which doesn't like being
called again. We should just do the dev put version instead.

This fixes some crashes unplugged in a udl device.
