[ Upstream commit 26dd6a5667f500c5d991f90a9ac5998a71afaf5c ] There's a Cirque touchpad that wakes system up without anything touched the touchpad. The input report is empty when this happens. The reason is stated in HID over I2C spec, 7.2.8.2: "If the DEVICE wishes to wake the HOST from its low power state, it can issue a wake by asserting the interrupt." This is fine if OS can put system back to suspend by identifying input wakeup count stays the same on resume, like Chrome OS Dark Resume [0]. But for regular distro such policy is lacking. Though the change doesn't bring any impact on power consumption for touchpad is minimal, other i2c-hid device may depends on SLEEP control power. So use a quirk to limit the change scope.
