[Qemu-devel] [PATCH v2 01/45] char: add qemu_chr_free()

[Marc-André Lureau]

From: Marc-André Lureau <address@hidden>

If a chardev is allowed to be created outside of QMP, then it must be
also possible to free it. This is useful for ivshmem that creates
chardev anonymously and must be able to free them.
