Hi Sir, Add patch to Atmel AC97C.

Object: using software reset instead hardware reset if not available

Could you repost with the patch so that it can be applied directly via git-am? I seem to have missed the original post during my traveling. You can put the acked-by tag by Nicolas there, too.

thanks,

Takashi

You may need to sent it to the sound subsystem mailing-list and maintainers.

Anyway, I let you follow this patch... As it is a fixup and will benefit to existing platforms, I think that it can make its way to mainline during 3.2 phase.

Best regards,
