CVE-2025-21783

Vulnerability Description

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

gpiolib: Fix crash on error in gpiochip_get_ngpios()

The gpiochip_get_ngpios() uses chip_*() macros to print messages.
However these macros rely on gpiodev to be initialised and set,
which is not the case when called via bgpio_init(). In such a case
the printing messages will crash on NULL pointer dereference.
Replace chip_*() macros by the respective dev_*() ones to avoid
such crash.
