Joonwoo Park a909e1258f ASoC: jack: Add API report sock jack without DAPM sync
Currently snd_soc_jack_report() always acquires codec->mutex and
synchronize DAPM widgets.  This automation is helpful if jack has defined
widget.  However if codec driver doesn't have defined jack widget and
non-jack widget wants to synchronize with report_sock_jack's thread which
is usually irq handler, it can make dead-lock as all DAPM widget
call-backs are called after codec->mutex acquisition.
Add new API snd_soc_jack_report_no_dapm() so codec driver can have ability
of control DAPM synchronization part of snd_soc_jack_report()
