Subject[PATCH] drm/nouveau: add missing single_release()
Date
When using single_open() for opening, single_release() should be
used, otherwise there is a memory leak.

This is detected by Coccinelle semantic patch.

Fixes: 6e9fc177399f ("drm/nouveau/debugfs: add copy of sysfs pstate interface ported to debugfs")
