Subject: [PATCH] alsa: Intel HDA output and align Ids.
Date: Mon, 23 Mar 2009 11:15:59 +0100 [thread overview]
Message-ID: <1237803359.11871.23.camel@carnifex> (raw)
This patch does two things:
Output Intel HDA Function Id in /proc/asound/cardX/codec#X
Align Vendor/Subsystem/Revision Ids to 8 characters, front-padded with zeros
Before:
Vendor Id: 0x11d41884
Subsystem Id: 0x103c281a
Revision Id: 0x100100
After:
Function Id: 0x1
Vendor Id: 0x11d41884
Subsystem Id: 0x103c281a
Revision Id: 0x0100100
As report on the Kernel Bugzilla #12888
