Subject: [PATCH] USB: serial: pl2303: fix GL type detection
Git-commit: dcf097e7d21fbdfbf20e473ac155f4d154018374
Patch-mainline: v5.15-rc1
References: git-fixes stable-5.14.2
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.
