Subject: [GIT PULL] USB-serial updates for 5.14-rc1

Hi Greg,

Here are the USB serial updates for 5.14-rc1.

Note that you'll get a merge conflict in cp210x between 

	6f7ec77cc8b6 ("USB: serial: cp210x: fix alternate function for CP2102N QFN20")

which is already in your tree and

	8051334e901f ("USB: serial: cp210x: add support for GPIOs on CP2108")

This was also reported by Stephen here

	https://lore.kernel.org/r/20210617150224.19213166@canb.auug.org.au

and the resolution should be straight forward.

Let me know if you prefer I pull in Linus's rc:s like you do to resolve any
issues like this in the future.

Johan
