CVE-2026-93274

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
