From b9acb64a385c5b26fc392e0d58ac7b8e0a2cd812 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Wed, 7 Jan 2009 16:37:35 +0100 Subject: hwmon: Check for ACPI resource conflicts Check for ACPI resource conflicts in hwmon drivers. I've included all Super-I/O and PCI drivers. I've voluntarily left out: * Vendor-specific drivers: if they conflicted on any system, this would pretty much mean that they conflict on all systems, and we would know by now. * Legacy ISA drivers (lm78 and w83781d): they only support chips found on old designs were ACPI either wasn't supported or didn't deal with thermal management. * Drivers accessing the I/O resources indirectly (e.g. through SMBus): the checks are already done where they belong, i.e. in the bus drivers.
