Merge tag 'tty-6.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty / serial fixes from Greg KH:
"Here are three small tty and serial driver fixes for 6.8-rc5:
- revert a 8250_pci1xxxx off-by-one change that was incorrect
- two changes to fix the transmit path of the mxs-auart driver,
fixing a regression in the 6.2 release
All of these have been in linux-next for over a week with no reported
issues"
* tag 'tty-6.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty:
serial: mxs-auart: fix tx
serial: core: introduce uart_port_tx_flags()
serial: 8250_pci1xxxx: partially revert off by one patch

- This kernel feature is useful for number crunching applications
- that may need to compute untrusted bytecode during their
- execution. By using pipes or other transports made available to
- the process as file descriptors supporting the read/write
- syscalls, it's possible to isolate those applications in
- their own address space using seccomp. Once seccomp is
- enabled via /proc/<pid>/seccomp, it cannot be disabled
- and the task is only allowed to execute a few safe syscalls
- defined by each seccomp mode.
