Re: [alsa-devel] [PATCH] ASoC: fsl_ssi: free irq before irq_dispose_mapping()

Would the mapping continue to exist after the driver is unloaded?  Can you
try multiple loads/unloads and see if interrupts still work?

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.
