Any reason to change?
Well, I think even the original phys value "ALSA" is a bit strange in comparison with values of other input drivers, such as "isa0060/serio0/input0", "PNP0C0C/button/input0", too... Mark, what do you think?

Does this have to be in hda_codec core now? Maybe later, but I feel it's too early to change the core side unless you really need it. Note that you may have multiple headphone, mic, line-in and whatever jacks. So, if any, it should be either an array or a list as a more generic representation.
And, if you add struct snd_jack there, include <sound/jack.h> in that header, or add a forward declaration of the struct.

Sorry, I don't want to put this into proc file. In some obscure hardwares, you can't call jack-detect verb always even if the pin shows it's possible, and it breaks the later jack-sense reading (believe nor not :) In some cases, it needs triggering. So, "just read" is dangerous.
BTW, this change has nothing to do with the addition of jack layer support. If this addition is inevitably necessary, please split to an individual patch.
Thanks,
