[PATCH] USB: serial: pl2303: fix GL type detection

From: Robert Marko <robert.marko@sartura.hr>
Date: 2021-08-26 11:02:56
Also in: lkml
Subsystem: the rest, usb serial subsystem, usb subsystem · Maintainers: Linus Torvalds, Johan Hovold, Greg Kroah-Hartman

At least some PL2303GL have a bcdDevice of 0x405 instead of 0x100 as the
datasheet claims. Add it to the list of known release numbers for the
HXN (G) type.
