USB-serial fixes for 5.10-rc7

Here's a fix for a regression in the option driver which has been
backported to the stable trees and fix for a small memory leak on open
in the kl5kusb105 driver.

Included are also various new device ids.

All but the memleak fix has been in linux-next and with no reported
issues.
