USB-serial updates for 4.21-rc1
Here are the USB-serial updates for 4.21-rc1, including: - support for mos7840 3-port devices - improved ftdi baud-rate divisor calculations - support for a new class of f81534 devices Included are also various clean ups and some new pl2303 device ids. All have been in linux-next with no reported issues.
