[PATCH 37/90] staging: comedi: amplc_pci230: cleanup "find pci device" code

From: H Hartley Sweeten
Date: Wed Jul 18 2012 - 21:41:52 EST


For aesthetic reasons, rename the function and pass the
comedi_devconfig struct instead of pre-parsing out the bus/slot
information.

Consolidate the dev_err messages when a pci device is not found.
