Subject: [PATCH] AC97: Print AC97 flags in proc file to make debug it easier
Date: Wed, 28 Jan 2009 15:39:22 -0200 [thread overview]
Message-ID: <1233164362-12635-1-git-send-email-cascardo@holoscopio.com> (raw)
While debugging some code paths in AC97 codec patches and its suspend
and resume functions, getting to know the flags has proved useful to
follow those code paths.
