Hi Greg, Here are the USB-serial updates for 5.12-rc1. Note that the new MaxLinear/Exar driver can also be used (with fewer features) in ACM-mode so this pull-request includes a commit to prevent cdc-acm from binding when the new driver is enabled. Johan The following changes since commit 7c53f6b671f4aba70ff15e1b05148b10d58c2837: Linux 5.11-rc3 (2021-01-10 14:34:50 -0800) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/johan/usb-serial.git tags/usb-serial-5.12-rc1 for you to fetch changes up to 1542d1324be1191d970f69c55e885af5dd810b84: USB: serial: drop bogus to_usb_serial_port() checks (2021-02-09 13:14:30 +0100) ---------------------------------------------------------------- USB-serial updates for 5.12-rc1 Here are the USB-serial updates for 5.12-rc1, including: - a line-speed fix for newer pl2303 devices - a line-speed fix for FTDI FT-X devices - a new xr_serial driver for MaxLinear/Exar devices (non-ACM mode) - a cdc-acm blacklist entry for when the xr_serial driver is enabled - cp210x support for software flow control - various cp210x modem-control fixes - an updated ZTE P685M modem entry to stop claiming the QMI interface - an update to drop the port_remove() driver-callback return value Included are also various clean ups.
