6.6-stable review patch. If anyone has any objections, please let me know.

From: Johan Hovold johan+linaro@kernel.org
commit 9feefbf57d92e8ee293dad67585d351c7d0b6e37 upstream.
Make sure to remove the software node also on (ACPI) probe errors to avoid leaking the underlying resources.
Note that the software node is only used for ACPI probe so the driver unbind tear down is updated to match probe.
