[RFC][PATCH 1/2] alsa: jack: expand snd_jack_report parameter for jack sw_inject

[Hui Wang]

This is the preparation for supporting jack software plug in/out
injection, when users enable the software injection, the jack state
shouldn't be changed by hw events or other non-injection events
anymore, so adding a parameter in the snd_jack_report() to distinguish
if the function is called from software injection or not.
