This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
commit 4adeb0ccf86a5af1825bbfe290dee9e60a5ab870 upstream.
max98090.c doesn't free the threaded interrupt it requests. This causes
an oops when doing "cat /proc/interrupts" after snd-soc-max98090.ko is
unloaded.
Fix this by requesting the interrupt by using devm_request_threaded_irq().
