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.
