USB-serial fixes for 5.14-rc8
Here's a fix for a regression in 5.14 (also backported to stable) which caused reads to stall for ch341 devices. Included is also a new modem device id. All but the revert have been in linux-next, and with no reported issues. -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQQHbPq+cpGvN/peuzMLxc3C7H1lCAUCYSdM5wAKCRALxc3C7H1l CLuRAQCZMmb7IlwfYjOBZNhF6Lf6IQX/VG6FPPVU/1dNF5v48gD+P1up9WXR7gyz WAl5/RKQJPqjvoY/weOvrle1oNJc5wc= =1F5W -----END PGP SIGNATURE----- Merge tag 'usb-serial-5.14-rc8' of https://git.kernel.org/pub/scm/linux/kernel/git/johan/usb-serial into usb-linus Johan writes: USB-serial fixes for 5.14-rc8 Here's a fix for a regression in 5.14 (also backported to stable) which caused reads to stall for ch341 devices.
