Subject: staging: comedi: drivers: use comedi_dio_update_state() for simple
cases
From: H Hartley Sweeten <[email protected]>
commit 97f4289ad08cffe55de06d4ac4f89ac540450aee upstream.
[Split from original patch subject: "staging: comedi: drivers: use
comedi_dio_update_state() for simple cases"]
Use comedi_dio_update_state() to handle the boilerplate code to update
the subdevice s->state for simple cases where the hardware is updated
when any channel is modified.
Also, fix a bug in the amplc_pc263 and amplc_pci263 drivers where the
current state is not returned in data[1].
