^^
are you sure this is ok?
in the case of emu10k1, it generates irq twice per buffer (HALF and
BUFFER). then periods_max must be 2.
anyway, the driver code is quite similar with emu10k1x.c.
i checked the diff between them and the amount of difference is really
small.
how about merging them? then we can understand / maintain the codes
better.
