[PATCH v3 07/15] remoteproc: xlnx: Use mbox_ring_doorbell() instead of NULL message

From: Douglas Anderson

Date: Mon Feb 16 2026 - 13:13:36 EST


As per the patch ("mailbox: Deprecate NULL mbox messages; Introduce
mbox_ring_doorbell()"), we want to switch all users of NULL mailbox
messages to use mbox_ring_doorbell().

This client only ever sent NULL message on the rx channel, so the
transition is straightforward.
