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

net: dsa: realtek: use gpiod_set_value_cansleep for reset GPIO

rtl83xx_reset_assert() and rtl83xx_reset_deassert() are only called from the probe path, which may sleep and is not timing-critical. When the reset GPIO is provided by a sleeping controller such as an I2C I/O expander, gpiod_set_value() warns:

Switch both helpers to gpiod_set_value_cansleep() so such a reset GPIO can be used without triggering the warning.

The reset GPIO has been driven with the non-sleeping gpiod_set_value() since the driver was added in v4.19. The call has since been refactored across several files - from realtek-smi.c / realtek-mdi…
