[PATCH 0/7] chardev: Improve @docstring and clarify qemu_chr_write() uses

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Few chardev fixes:
- preserve %errno
- allow partial writes in qemu_chr_write()

Improve chardev methods documentation.

While @c for frontend and @s for backend is accepted, it
confuses me, so I prefer to document for my own mental health.

Based-on: <20251022074612.1258413-1-marcandre.lureau@redhat.com>
