From 42100e306c0a33f56a079645148d6ceed17d2c40 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 18 Nov 2015 10:07:16 -0700 Subject: staging: comedi: adv_pci_dio: do board reset early in (*auto_attach) The board reset function disables and clears all interrupts. It also resets all the digital output channels to 0. Interrupts are not currently used by this driver. For asthetics, do the board reset early in the (*auto_attach) to make sure the interrupts are disabled in case this feature is added.
