SubjectRe: [PATCH] for YMF PCI sound cards
Hello, Pete!

Ok, I'm not a good kernel hacker. I simply did what I believed would be
the behaviour that minimizes the number of gotchas for the end user. If
the instance number isn't reliable then drop it and initialize OPL for all

The users of multiple cards will have to supply synth_io, but I wouldn't
fight to save few keystrokes for the insane people with more than one YMF
soundcard :-)

The later is better. I never know whether I'll have a free minute in a
couple of weeks.

I have no documents, only the log from the patched module:

Dec 8 13:29:35 fonzie kernel: ymfpci0: YMF740C at 0xf0000000 IRQ 10
Dec 8 13:29:35 fonzie kernel: ymfpci0: set OPL3 I/O at 0x388
Dec 8 13:29:36 fonzie kernel: ac97_codec: AC97 Audio codec, id:
0x4144:0x5303 (Yamaha YMF????)

Drop it if it's not convincing.
