From cee3583dda452baef74a60ac9091575e8b09326a Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 18 Nov 2015 10:07:16 -0700 Subject: [PATCH] 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.
