From: Johan Hovold <johan@xxxxxxxxxx> This patch has been added to the 3.12 stable tree. If you have any objections, please let us know. =============== 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.
