Guangshuo LiandGreg Kroah-Hartman c947360ae6 usb: musb: omap2430: Do not put borrowed of_node in probe
omap2430_probe() stores pdev->dev.of_node in a local np variable. This is
a borrowed pointer and the probe function does not take a reference to
it.

The success and error paths nevertheless call of_node_put(np). This drops
a reference that is owned by the platform device, and can leave
pdev->dev.of_node with an unbalanced reference count.

Do not put the borrowed platform device node from omap2430_probe().
References taken for the child MUSB device are handled by the device core,
and the ctrl-module phandle reference is still released separately.
