Subject: [PATCH] remoteproc: imx_rproc: Fix a resource leak in the remove
function

'priv->workqueue' is destroyed in the error handling path of the probe but not
in the remove function.

Add the missing call to release some resources.

Fixes: 2df7062002d0 ("remoteproc: imx_proc: enable virtio/mailbox")

Thank you for that - I will pick up this patch when -rc1 or -rc2 gets released.

Thanks,
Mathieu

This patch is speculative. I'm not sure if the added function call is at the right
place in the remove function.
Review with care.
