From d97e1552fd71e7ba512c626f5c90afa331c48cec Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 18 Nov 2015 10:07:32 -0700 Subject: [PATCH] staging: comedi: adv_pci_dio: move pci_dio_override_cardtype() This function is called as part of the pci_driver (*probe) before doing the (*auto_attach) of the comedi driver. For aesthetics, move the function to a more logical place in the driver.
