The jack-detect support for the WM5102 codec is handled by the extcon-arizona driver. This driver exports info about the jack state to userspace through the standard extcon sysfs class interface. But standard Linux userspace does not monitor/use the extcon sysfs interface for jack-detection. The extcon-arizona driver can also report jack-detect state through the standard ASoC jack interface. For this we need to create a snd_soc_jack and pass this to the extcon-arizona driver through the shared arizona data struct. The extcon-arizona code already depends on (waits for with -EPROBE_DEFER) the snd_card being registered by the machine driver, so this does not cause any ordering issues.
