USB: serial: pl2303: fix GC type detection
At least some PL2303GC have a bcdDevice of 0x105 instead of 0x100 as the datasheet claims. Add it to the list of known release numbers for the HXN (G) type. Note the chip type could only be determined indirectly based on its package being of QFP type, which appears to only be available for PL2303GC. Fixes: 894758d0571d ("USB: serial: pl2303: tighten type HXN (G) detection") Cc: stable@vger.kernel.org # 5.13 Reported-by: Anton Lundin <glance@acc.umu.se> Link: https://lore.kernel.org/r/20211123071613.GZ108031@montezuma.acc.umu.se Link: https://lore.kernel.org/r/20211123091017.30708-1-johan@kernel.org Signed-off-by: Johan Hovold <johan@kernel.org>
