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

From: Johan Hovold johan+linaro@kernel.org
commit c948ff727e25297f3a703eb5349dd66aabf004e4 upstream.
To make sure that the controller is runtime resumed and its power domain is enabled before accessing its registers during probe, the synchronous runtime PM interface must be used.
