I'm not convinced to pollute the kernel space with this code. You can use
LD_PRELOAD and simulate this via a shared library or the alsa-lib may be extended.

Also, the first patch can be omitted if you just create another
snd_jack_report() function for the user API and put the common code to the
static function in jack.c.
