From 8c287d2053c28b838de557ce5319acbd6e4bb627 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Mon, 26 Mar 2012 16:57:26 +0100 Subject: [PATCH] staging: comedi: amplc_dio200: separately configure ISA and PCI The amplc_dio200 driver supports both ISA and PCI cards, but currently it is only possible to select the driver if PCI is configured. This patch splits the configuration to make the ISA and PCI parts seperately selectable, and changes the driver to only include the selected ISA and/or PCI board types.
