It does. Acked/Tested-by: Rene Herman <rene.herman at gmail.com>

This bug was uncovered by !CONFIG_PNP and we had trouble in this driver 
due to that before so was rewriting the init to be a generic multi-card 
ALSA init but, actually, not much point.

The hardware fundamentally doesn't support more than one card per system 
due to the fixed chip->mc_base and the bug was in this case not _caused_ 
but only uncovered by !CONFIG_PNP (it triggers for CONFIG_PNP after 
supplying "isapnp=0" as a module param) so I'll just wait for the next 
time this ifdeffed together mess breaks on !CONFIG_PNP to make the init 
look generic ;-)

In fact, in the meantime I'll look at splitting 92x and 93x again. It's 
much better now that Krzysztof made it use the generic library code but 
I still hate this driver. It's also poking at ports without being told 
something is there by either system or user.

Trivial remainder of init rewrite that's still applicable:
