Subject[PATCH 2/2] drm/nouveau/debugfs: fix file release memory leak
Date
When using single_open() for opening, single_release() should be
called, otherwise the 'op' allocated in single_open() will be leaked.

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