From 934efe63e8bece28c69d18ea5e3bfd1619fc23b2 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 21 Jan 2013 15:17:05 -0700 Subject: [PATCH] staging: comedi: addi_apci_2200: use addi_watchdog module The current watchdog support in hwdrv_apci2200.c does not conform to the comedi API. Use the addi_watchdog module to provide support for the watchdog subdevice and remove the now unneeded hwdrv_apci2200.c file.
