Date: Fri, 23 Oct 2026 05:32:27 +0000 [thread overview]

> The driver creates a serdev client without firmware metadata and
> force-attaches its driver to it.
>
> Set the modalias of the client before adding it and give the serdev
> driver a matching id_table, so that the serdev core binds the two
> through normal matching, then drop the manual attachment.
>
> The client now also reports a "serial:dell_uart_backlight" modalias to
> userspace instead of failing with -ENODEV. A failing serdev probe no
> longer propagates out of the platform probe; as for any other bus, the
> client is simply left unbound.
