[PATCH 09/11] extcon: arizona: Clear _trig_sts bits after jack detection

From: Mark Brown
Date: Mon Feb 11 2013 - 11:28:52 EST


From: Charles Keepax <ckeepax@xxxxxxxxxxxxxxxxxxxxxxxxxxx>

It is important to clear the wake trigger status bits otherwise DCVDD
will be held high independent of the state of the LDOENA line.
