[PATCH v2] hw/char: clear dangling GLib event source tag

[PATCH v2] hw/char: clear dangling GLib event source tag

[Matthew Penney]

Clear dangling GLib event source tag when virtio-console is
unrealized. This prevents a stale tag from being used, and
maintains consistency with the rest of virtio-console.

v2:
Use g_clear_handle_id() per advice from Marc-André Lureau

Hi,

Just a gentle ping regarding the v2 patch I sent a couple of weeks ago.
Patchew: https://patchew.org/QEMU/20260305213308.96441-1-matt@matthewpenney.net/

Thanks for your time.

Best regards,
