Hi Takashi.
After the change to the platform_driver stuff in 2.6.16, all ISA card
module_inits loop over the cards using:
for (i = 0; i < SNDRV_CARDS && enable[i]; i++) {
This means that the driver bails completely on the first !enable[i].
This did not use to be the case and does not seem right. I believe it
should rather be:
for (i = 0; i < SNDRV_CARDS; i++) {
if (!enable[i])
continue;
This would restore the previous behaviour for the enable parameter; ie,
only ignore the one.
Assuming this was indeed the idea, I've attached a patch against 2.6.16.
If it's correct, but you need it against ALSA CVS instead, please say so
