[PATCH 01/90] staging: comedi: comedidev.h: introduce comedi_to_pci_dev() helper

From: H Hartley Sweeten
Date: Wed Jul 18 2012 - 21:24:19 EST

Introduce a wrapper for to_pci_dev() to allow the comedi pci drivers
to store the pci_dev pointer in the comedi_device hw_dev variable and
retrieve it easily.
