From 868d1721a2200244a4555193d4adc1133cfb3978 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Wed, 4 May 2011 10:18:42 +0100 Subject: parport: Use request_muxed_region for IT87 probe and lock This is needed as part of making the various IT87 drivers actually co-exist politely with each other, and with other superio devices that may be muxed on 0x2E/0x2F. It can be applied before or after the other patches by Nat Gurumoorthy without problem.
