Commit f04f03d3e99b ("Input: synaptics - enable SMBus for HP Elitebook 850 G1= ") added PNP ID "SYN3003" to smbus_pnp_ids[] to enable SMBus/InterTouch mode. However, on Haswell-generation HP EliteBooks sharing this touchpad controller (including HP EliteBook 840 G1 and HP EliteBook 850 G1), the touchpad fails to resume after ACPI S3 suspend: rmi4_smbus 0-002c: failed to get SMBus version number! rmi4_f01 rmi4-00.fn01: Resume failed with code -6. rmi4_physical: Failed to resume rmi4-00: -6 Following resume from suspend, the touchpad remains completely unresponsive and dead until a full reboot or manual module reload (modprobe -r psmouse). Falling back to standard PS/2 mode (via synaptics_intertouch=3D0) allows multi-touch gestures (two-finger scrolling, tap-to-click) to function normally while preserving 100% reliable S3 suspend/resume behavior. Revert this commit to prevent this regression on affected hardware.
