From e40e8375c0eb546b66c5e66f5e10b68ec46f7b95 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 13 Jun 2012 15:41:27 -0700 Subject: [PATCH] staging: comedi: 8255: use pointer to dev->subdevices Instead of accessing the dev->subdevices directly as an array, use a pointer. This method is more common in the comedi subsystem.
