[PATCH 5.15 004/913] USB: serial: pl2303: fix GS type detection

From: Greg Kroah-Hartman
Date: Tue Apr 05 2022 - 10:33:07 EST

From: Johan Hovold <johan@xxxxxxxxxx>

commit 5b6ab28d06780c87320ceade61698bb6719c85db upstream.

At least some PL2303GS have a bcdDevice of 0x605 instead of 0x100 as the
datasheet claims. Add it to the list of known release numbers for the
HXN (G) type.
