From 4190c22008ef241cd9ae791bd9934e16c563fbc4 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 18 Nov 2015 10:07:15 -0700 Subject: [PATCH] staging: comedi: adv_pci_dio: remove board reset during (*detach) The board reset function disables and clears all interrupts. It also resets all the digital output channels to 0. Interrupts are not used by this driver so the disable/clear during the (*detach) is not necessary. Reseting all the digital outputs to 0 might not be desired depending on what the outputs are connected to. Remove the board reset and just use comedi_pci_detach() directly for the driver (*detach).
