4.3-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <johan@kernel.org>
commit 157f38f993919b648187ba341bfb05d0e91ad2f6 upstream.
Fix parent-device reference leak due to SPI-core taking an unnecessary reference to the parent when allocating the master structure, a reference that was never released.
Note that driver core takes its own reference to the parent when the master device is registered.
