On some old IBM workstations and desktop computers, the BIOS presents in the DSDT an SMBus object that is missing the HID identifier that the i2c-scmi driver looks for. Modify the ACPI device scan code to insert the missing HID if it finds an IBM system with such an object. Affected machines: IntelliStation Z20/Z30. Note that the i2c-i801 driver no longer works on these machines because of ACPI resource conflicts. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
