Subject: [PATCH] regulator: bd9571mwv: fix OF node reference imbalance

The driver reuses the OF node of the parent multi-function device but fails to take another reference to balance the one dropped by the platform bus code when unbinding the MFD and deregistering the child devices.

Fix this by using the intended helper for reusing OF nodes.
