Description
In the Linux kernel, the following vulnerability has been resolved:
ALSA: jack: Access input_dev under mutex
It is possible when using ASoC that input_dev is unregistered while
calling snd_jack_report, which causes NULL pointer dereference.
In order to prevent this serialize access to input_dev using mutex lock.
