[PATCH 1/2] phy: tegra: xusb: fix device release in tegra210_xusb_padctl_probe

[Javier Carrasco]

A reference to a device acquired via of_find_device_by_node() needs
to be released when it is no longer required by decrementing its
refcount, which avoids leaking the resource.

Add the missing call to platform_device_put() as soon as 'pdev' is no
longer required.
