[PATCH 00/24] tty/serial: a bunch of llm-found fixes

[Greg Kroah-Hartman]

Here's a series of some small llm-found fixes that have been sent to me
recently.  Most of them are just minor bugfixes and locking cleanups,
but they are good to have from what I can tell.

Submitting them here to get a solid Sashiko run and some second eyes on
them before merging if all goes well.
