Hi, sorry for the delay.

I've tested the http://linuxtv.org/hg/~stoth/cx23885-audio tree and it 
doesn't work well.

You seem to have removed a piece from my patch that avoids some register
modification in cx25840-core.c:cx23885_initialize()

-       cx25840_write(client, 0x2, 0x76);
+       if (state->rev != 0x0000) /* FIXME: How to detect the bridge 
type ??? */
+               /* This causes image distortion on a true cx23885 board */
+               cx25840_write(client, 0x2, 0x76);

As the patch says that register write causes a horrible image distortion
on my HVR-1500 which has a real cx23885 (not 23887, 23888, etc) board.

I don't know if it's really required for any bridge as everything seems
to be auto-configured by default, maybe it can be simply dropped.

Other than that the cx23885-audio tree works well.

WRT the whitespaces, 80 cols, etc; most are also in the sources I took
as basis, so I didn't think they were a problem.
