Subject[PATCH 2/2] staging: comedi: addi_apci_1564: use addi_watchdog module to init watchdog subdevice
Date
Use the addi_watchdog module to provide support for the watchdog
subdevice.

Also, rearrange the subdevice init blocks so that the order makes sense.
Digital input/output subdevices and subdevices for DI/DO interrupt
support, followed by timer/counter/watchdog subdevices is the new order.
