Merge tag 'usb-serial-5.16-rc6' of https://git.kernel.org/pub/scm/linux/kernel/git/johan/usb-serial into usb-linus
Johan writes: USB-serial fixes for 5.16-rc6 Here's a fix for a reported problem in the cp210x gpio-registration code and some more modem device ids. All have been in linux-next with no reported issues. * tag 'usb-serial-5.16-rc6' of https://git.kernel.org/pub/scm/linux/kernel/git/johan/usb-serial: USB: serial: option: add Telit FN990 compositions USB: serial: cp210x: fix CP2105 GPIO registration
