In the Linux kernel, the following vulnerability has been resolved:

pinctrl: bcm2835: Don't remove an unregistered GPIO chip

If the devm_pinctrl_register() function fails,
bcm2835_pinctrl_probe() calls gpiochip_remove()
before gpiochip_add_data() has registered the GPIO chip.

This means that upon failure the gpio_chip.gpiodev
is NULL resulting in a null pointer dereference
inside the gpiochip_remove() function.

Remove the unnecessary function call to gpiochip_remove().
No GPIO cleanup is required because the GPIO chip
has not yet been registered. Without this change there
is potential for a kernel panic upon registration failure
