Okay, you misinterpreted the SoC's GPIO with external component. The problem is
you forgot (or distro, in that case file a bug in their respective bugzilla) to
have the proper LJCA driver(s) be enabled.

Another possibility that they are using old kernel.

You can spent 5 minutes by checking yourself:

$ git grep -n -w INTC10B5
drivers/gpio/gpio-usbio.c:31: { "INTC10B5" }, /* LNL */
drivers/usb/misc/usb-ljca.c:182: { "INTC10B5" }, /* LNL LJCA GPIO */

Overall, your series is not needed at all.
