From e0d7e2690fd3aff73283a885cb9d077ea3830aba Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Fri, 19 Aug 2016 23:41:32 +0300 Subject: intel/i82801gx 82801ix: Remove OpRegion of SMBus host MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Defining this OpRegion for SMBus controller prevents linux kernel driver i2c-i801 from registering SMBus under sysfs, with following error in dmesg: ACPI Warning: SystemIO range .. conflicts with OpRegion .. (\_SB.PCI0.SBUS.SMBI) Solution taken from intel/bd82x6x. Worth noting we do not define ENABLE_SMBUS_METHODS anywhere currently. Removed remaining reference to HSTS from GETAC P470.
