From 16dd84f52c2dea55870ed9293e74ce61e3d405c2 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 18 Jul 2012 18:49:35 -0700 Subject: [PATCH] staging: comedi: cb_pcimdas: store the pci_dev in the comedi_device Use the hw_dev pointer in the comedi_device struct to hold the pci_dev instead of carrying it in the private data.
