If I need to call a codec driver function whenever Headset status
changes (to set various registers, turn off micbias etc.). In such a
case, can the jack_status_check callback in snd_soc_jack_gpio structure
be used? If I use it, I would need to modify the callback to pass
certain parameters (codec pointer, status). Is this the intended use of
the callback?

I rather suspect you shouldn't be doing that and should be doing
something else instead (probably using the notifiers) but without seeing
what you're trying to accomplish it's hard to comment in detail.
