Description

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