From: Niklas Söderlund <niklas.soderlund+renesas@xxxxxxxxxxxx> [ Upstream commit 39056e8a989ef52486e063e34b4822b341e47b0e ] If the common register memory resource is not available the driver needs to fail gracefully to disable PM. Instead of returning the error directly store it in ret and use the already existing error path.
