In the Linux kernel, the following vulnerability has been resolved: gpio: tegra: do not call pinctrl for GPIO direction tegra_gpio_direction_input() and tegra_gpio_direction_output() already program the GPIO controller direction registers directly. The additional pinctrl_gpio_direction_input/output() calls do not add a Tegra pinctrl operation, because the Tegra pinmux ops provide GPIO request/free handling but no gpio_set_direction hook. The extra call still enters the pinctrl core and takes…
