[PATCH 6.1 217/609] media: vpif_capture: fix OF node reference imbalance

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

------------------

From: Johan Hovold <[email protected]>

commit 2282f979560af6bbc8ee2c1ee8663197312cee5b upstream.

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

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