Right, I missed that in my review. Not sure if this was a mistake in my original patch or if it started in a later version.
I think for the ISA drivers, I would still add 'depends on HAS_IOPORT' to both CONFIG_SND_ISA and CONFIG_SND_OPL3_LIB if only to make it easier to understand, even though CONFIG_ISA requires HAS_IOPORT already, and CONFIG_SND_OPL3_LIB cannot be selected by itself.
Yes, that makes sense.
For the PCI drivers, I think we need to add the same dependency on anything that either selects SND_OPL3_LIB or calls inb()/outb() directly.
Agreed.
