From: H Hartley Sweeten Date: Fri, 30 Aug 2013 18:08:50 +0000 (-0700) Subject: staging: comedi: ssv_dnp: use comedi_dio_update_state() X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=4d72984a5893a40e0990080d6036646a688cd493;p=linux-edison.git staging: comedi: ssv_dnp: use comedi_dio_update_state() commit f6b316bcd8c421acd6fa5a6e18b4c846ecb9d965 upstream. Use comedi_dio_update_state() to handle the boilerplate code to update the subdevice s->state. Also, fix a bug where the state of the channels is returned in data[0]. The comedi core expects it to be returned in data[1].
