If anyone has any objections, please let me know. ------------------ From: Nicolás Bazaes commit 16ca52bc209fa4bf9239cd9e5643e95533476b58 upstream. The Lenovo ThinkPad E490 (PNP ID: LEN2058) has a Synaptics TM3471-020 touchpad that supports SMBus/RMI4 mode but is not listed in smbus_pnp_ids[]. Without this entry, RMI4 over SMBus is not enabled by default, and the touchpad falls back to PS/2 mode. Adding LEN2058 to the passlist enables automatic RMI4 detection without requiring the psmouse.synaptics_intertouch parameter, and matches the behavior of similar ThinkPad models already in the list (E480/LEN2054, E580/LEN2055). Tested on ThinkPad E490 with kernel 7.0.5-zen1 and Arch Linux. RMI4 over SMBus is confirmed working without any kernel parameters.
