Russell King b60fb519d7 ALSA: AACI: fix multiple IRQ claiming
Claiming the IRQ each time a playback or capture interface is opened
is wasteful; the second copy of the registered handler is identical to
the first and just wastes resources.  Track the number of opens and
only register the handler when necessary.
