Merge tag 'tty-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty/serial updates from Greg KH:
"Here is the big set of tty and serial driver changes for 6.16-rc1.

A little more churn than normal in this portion of the kernel for this
development cycle, Jiri and Nicholas were busy with cleanups and
reviews and fixes for the vt unicode handling logic which composed
most of the overall work in here.

Major changes are:

- vt unicode changes/reverts/changes from Nicholas. This should help
out a lot with screen readers and others that rely on vt console
support

- lock guard additions to the core tty/serial code to clean up lots
of error handling logic

- 8250 driver updates and fixes

- device tree conversions to yaml

- sh-sci driver updates

- other small cleanups and updates for serial drivers and tty core
portions

All of these have been in linux-next for 2 weeks with no reported issues"

vt: support Unicode recomposition

Try replacing any decomposed Unicode sequence by the corresponding
recomposed code point. Code point to glyph correspondance works best
after recomposition, and this apply mostly to single-width code points
therefore we can't preserve them in their decomposed form anyway.

This removes the table from ucs.c and substitutes the generated tables

Also implements ucs_is_zero_width() to query the new zero-width table.
