[PATCH] AWACS driver, missing macro

[Giuliano Pochini <pochini@shiny.it>]

(Sorry if you already received this message, but all mail I
send to alsa-devel from my ISP's smtp server bounces. I'm
sending this through the server at work)



In the pmac AWACS driver of ALSA-1.0.6a there are two references to
num_controls():

[Giu@Jay ppc]$ grep num_controls *
awacs.c:                err = build_mixers(chip, num_controls(snd_pmac_screamer_mixers2),
awacs.c:                err = build_mixers(chip, num_controls(snd_pmac_awacs_mixers2),

But it is not defined anywhere. The following patch restores that macro that
I took from ALSA 1.0.5a. It looks fine here, too.  Tested ok (dual G4-MDD
with Snapper audio).
