Pull tty and serial driver updates from Greg KH: "Here is the big set of tty and serial driver updates for 5.13-rc1. Actually busy this release, with a number of cleanups happening: - much needed core tty cleanups by Jiri Slaby - removal of unused and orphaned old-style serial drivers. If anyone shows up with this hardware, it is trivial to restore these but we really do not think they are in use anymore. - fixes and cleanups from Johan Hovold on a number of termios setting corner cases that loads of drivers got wrong as well as removing unneeded code due to tty core changes from long ago that were never propagated out to the drivers - loads of platform-specific serial port driver updates and fixes - coding style cleanups and other small fixes and updates all over the tty/serial tree. All of these have been in linux-next for a while now with no reported issues" * tag 'tty-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (186 commits) serial: extend compile-test coverage serial: stm32: add FIFO threshold configuration dt-bindings: serial: 8250: update TX FIFO trigger level dt-bindings: serial: stm32: override FIFO threshold properties dt-bindings: serial: add RX and TX FIFO properties serial: xilinx_uartps: drop low-latency workaround serial: vt8500: drop low-latency workaround serial: timbuart: drop low-latency workaround serial: sunsu: drop low-latency workaround serial: sifive: drop low-latency workaround serial: txx9: drop low-latency workaround serial: sa1100: drop low-latency workaround serial: rp2: drop low-latency workaround serial: rda: drop low-latency workaround serial: owl: drop low-latency workaround serial: msm_serial: drop low-latency workaround serial: mpc52xx_uart: drop low-latency workaround serial: meson: drop low-latency workaround serial: mcf: drop low-latency workaround serial: lpc32xx_hs: drop low-latency workaround ...

speakup: i18n: Switch to kmemdup_nul() in spk_msg_set()

Use kmemdup_nul() helper instead of open-coding to simplify the code in spk_msg_set(). Reported-by: Hulk Robot Signed-off-by: Yang Yingliang Link: https://lore.kernel.org/r/20210406034434.442251-1-yangyingliang@huawei.com Signed-off-by: Greg Kroah-Hartman

tty: remove TTY_LDISC_MAGIC

2021-03-10T08:34:06Z

First, it is never checked. Second, use of it as a debugging aid is at least questionable. With the current tools, I don't think anyone used this kind of thing for debugging purposes for years. On the top of that, e.g. serdev does not set this field of tty_ldisc_ops at all. So get rid of this legacy.

speakup: Make dectlk flush timeout configurable

2021-02-04T16:05:48Z

In case the serial port or cable got faulty, we may not be getting acknowledgements any more. The driver then currently waits for 4s to avoid jamming the device. This makes this delay configurable.

speakup: Reference synth from tty and tty from synth

2021-01-27T12:12:04Z

We do not actually need speakup_tty and spk_ttyio_synth global variables, the synth can store the pointer to the tty, and the tty ldisc_data can store the pointer to the synth. Along the way, we can clench the initialization of the synth and the creation of the tty, so that tty is never NULL. Even if the device disappears (e.g. USB unplug), the tty structure will still be there, and we automatically stop speakup in the spk_ttyio_out error handler but keep tty until the user cleans things up. As a result, this simplifies locking a lot. Signed-off-by: Samuel Thibault Link: https://lore.kernel.org/r/20210126222147.3848175-3-samuel.thibault@ens-lyon.org Signed-off-by: Greg Kroah-Hartman

tty: rename tty_kopen() and add new function tty_kopen_shared()

2020-12-28T15:09:11Z

Introduce a new function tty_kopen_shared() that yields a struct tty_struct. The semantic difference to tty_kopen() is that the tty is expected to be used already. So rename tty_kopen() to tty_kopen_exclusive() for clearness, adapt the single user and put the common code in a new static helper function. tty_kopen_shared is to be used to implement an LED trigger for tty devices in one of the next patches.
