Dont create input devices for phantom jacks. Here, we extend snd_jack_new() to support phantom jack creating: pass in a bool param for [non-]phantom flag, and a bool param initial_jack to indicate whether we need to create a kctl at this stage. We can also add a kctl to the jack after its created meaning we can now integrate the HDA and ASoC jacks. Signed-off-by: Jie Yang <yang.jie@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
