i2c: Check for ACPI resource conflicts
Check for ACPI resource conflicts in i2c bus drivers. I've included all recent SMBus master drivers for PC hardware. I've voluntarily left out: * Drivers that don't run on PCs: they can't conflict with ACPI. * Bit-banged bus device drivers: it's very unlikely that ACPI would deal with such buses. Signed-off-by: Jean Delvare <jdelvare@suse.de>
