USB-serial updates for 6.5-rc1
Here are the USB-serial updates for 6.5-rc1, including: - improved error handling for break signalling - report to user space when a device does not support break signalling Included are also some new modem device ids. All have been in linux-next with no reported issues. -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQQHbPq+cpGvN/peuzMLxc3C7H1lCAUCZJVE7gAKCRALxc3C7H1l CMh6AQCB5nlSW3qScrAgH8k2drm2PNX+LLby6XFq6aSx5ZzN7gEAtXAqAcpd2X0R ZiFgQSlHyw/Fr1To/3htWHk0iIoSeg4= =MavO -----END PGP SIGNATURE----- Merge tag 'usb-serial-6.5-rc1' of https://git.kernel.org/pub/scm/linux/kernel/git/johan/usb-serial into usb-next Johan writes: USB-serial updates for 6.5-rc1 Here are the USB-serial updates for 6.5-rc1, including: - improved error handling for break signalling - report to user space when a device does not support break signalling Included are also some new modem device ids.
