I tried multiple loads/unloads and audio works fine with those changes.

About the ssi irq we have:

- With the ssi driver loaded:
root@freescale /home$ cat /proc/interrupts | grep ssi
79: 0 0 0 0 GIC 79 202c000.ssi

- After removing the ssi driver:
root@freescale /home$ rmmod snd-soc-fsl-ssi
root@freescale /home$ cat /proc/interrupts | grep ssi
root@freescale /home$

,so it seems to behave properly.
