From: Cryolitia PukNgae <Cryolitia@xxxxxxxxx> Some GPD devices ship a buggy firmware that describes on-device BMI260 with ACPI ID "BMI0160". Since this is fixed in BIOS update v0.40[1], let's match the correct ID to detect the device. The buggy ID "BMI0160" is kept as well to maintain compatibility with older firmwares. --- Some GPD devices ship a buggy firmware that describes on-device BMI260 with ACPI ID "BMI0160".
