spi: fix parent-device reference leak
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. Fixes: 49dce689ad4e ("spi doesn't need class_device") Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org
