spi: fix use-after-free at controller deregistration
commit 67f7b2781fafcc0f52464880154b320fea1ae982 upstream. The controller is typically freed as part of device_unregister() so store the bus id before deregistration to avoid use-after-free when the id is later released. Fixes: 9b61e302210e ("spi: Pick spi bus number from Linux idr or spi alias") Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
