USB-serial updates for 5.8-rc1

Here are the USB-serial updates for 5.8-rc1, including:

- a SPDX comment-style clean up
- a fix usb_wwan modem drivers which could end up resubmitting the their read URBs in a tight loop on disconnect
- a regression fix for a subset of quirky ch341 devices which would lock up on certain low line speeds when using the new divisor algorithm

All have been in linux-next with no reported issues.
