Description
In the Linux kernel, the following vulnerability has been resolved:
spi: meson-spicc: Fix double-put in remove path
meson_spicc_probe() registers the controller with
devm_spi_register_controller(), so teardown already drops the
controller reference via devm cleanup.
Calling spi_controller_put() again in meson_spicc_remove()
causes a double-put.
