[PATCH 3.14 057/114] ASoC: max98090: Fix missing free_irq

From: Greg Kroah-Hartman
Date: Mon Sep 15 2014 - 16:23:34 EST


3.14-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().
