CVE-2025-21783

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> gpiolib: Fix crash on error in gpiochip_get_ngpios()<br /> <br /> The gpiochip_get_ngpios() uses chip_*() macros to print messages.<br /> However these macros rely on gpiodev to be initialised and set,<br /> which is not the case when called via bgpio_init(). In such a case<br /> the printing messages will crash on NULL pointer dereference.<br /> Replace chip_*() macros by the respective dev_*() ones to avoid<br /> such crash.
