From 9bfa0d548c0ca427cba4a1c26658f870cfda64ca Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Wed, 24 Oct 2012 16:48:00 +0100 Subject: [PATCH] staging: comedi: amplc_dio200: set dev->iobase before common attach Don't pass the I/O base address to `dio200_common_attach()`. The only thing it does with it is set `dev->iobase` to the passed in value. Do that before calling `dio200_common_attach()` in order to simplify upcoming support for different register access methods.
