The BSG1160 ACPI HID is a HID describing a sensor complex consisting of 3 sensors: Accel: BMC150A at addr 0x11 Gyro: BMG160 at addr 0x68 Magneto: BMC150B at addr 0x13 A previous patch on this series has added the BSG1160 HID to the i2c_acpi_multiple_devices_ids list, so that one i2c_client gets instantiated per sensor. This commit not only adds the BSG1160 HID to the bmc150 code, but it also makes the i2c probe function check the client address for devices with a BSG1160 HID and only bind to the one at address 0x13.
