The following changes since commit 519d81956ee277b4419c723adfb154603c2565ba: Linux 5.15-rc6 (2021-10-17 20:00:13 -1000) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git tags/tty-5.16-rc1 for you to fetch changes up to cc8d7b4aea79df7cb45b74f9bc5b8a8bd2ed4c07: tty: Fix extra "not" in TTY_DRIVER_REAL_RAW description (2021-10-30 11:02:00 +0200) ---------------------------------------------------------------- TTY / Serial driver update for 5.16-rc1 Here is the big set of tty and serial driver updates for 5.16-rc1. Nothing major in here at all, just lots of tiny serial and tty driver updates for various reported things, and some good cleanups. These include: - more good tty api cleanups from Jiri - stm32 serial driver updates - softlockup fix for non-preempt systems under high serial load - rpmsg serial driver update - 8250 drivers updates and fixes - n_gsm line discipline fixes and updates as people are finally starting to use it. All of these have been in linux-next for a while now with no reported issues.
