Subject: [PATCH] drm/i915: convert debugfs creation/destruction to table
Date: Thu,  4 Jul 2013 20:39:49 +0200	[thread overview]
Message-ID: <1372963189-2071-1-git-send-email-daniel.vetter@ffwll.ch> (raw)

At least for the common cases where we only need special file
operations. The forcewake file is still rather more special.

v2: Fix up the debugfs unregister code.
