From 6746dc6340ea90e04f51825042d4e5e47472b951 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 30 Jan 2013 16:46:39 -0700 Subject: [PATCH] staging: comedi: ni_daq_dio24: cleanup dio24_detach Simplify the call to subdev_8255_cleanup() to remove the need for a local variable. This driver only attaches to pcmcia devices so the test for thisboard != pcmcia_bustype will always fail. Remove the test and the unreachable release_region(). This driver also never does a request_irq() so remove the free_irq().
