[PATCH 3.16 083/158] ASoC: max98090: Fix missing free_irq

[Greg Kroah-Hartman]

3.16-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jarkko Nikula <jarkko.nikula@xxxxxxxxxxxxxxx>

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().
