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.
Affected configurations
• linux linux kernel (>= 6.6 < 6.6.79)
• linux linux kernel (>= 6.7 < 6.12.16)
• linux linux kernel (>= 6.13 < 6.13.4)
• linux linux kernel 6.14
