Subject: [resent patch] add tda9887 module
Date: Wed, 8 Jan 2003 12:06:39 +0100 [thread overview]
Message-ID: <20030108110638.GA9067@bytesex.org> (raw)
Hi,
This patch adds the tda9887 i2c module to the linux kernel. This one
is needed for some TV cards. The patch also adds the missing #define
to audiochip.h which currently breaks the bttv build.
Please apply,
Gerd
