5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peng Fan <peng.fan@xxxxxxx>
[ Upstream commit 858e57c1d3dd7b92cc0fa692ba130a0a5d57e49d ]
Initialize workqueue before requesting mailbox channel, otherwise if
mailbox interrupt comes before workqueue ready, the imx_rproc_rx_callback
will trigger issue.
Fixes: 2df7062002d0 ("remoteproc: imx_proc: enable virtio/mailbox")
