From: Maksim Kiselev <[email protected]>
Since GCC 14 -Werror=implicit-function-declaration is enabled by default.
This leads to following compilation error:
drivers/gpio/mcp230xx_gpio.c:57:9: error:
implicit declaration of function ‘udelay’
[-Wimplicit-function-declaration]
57 | udelay(1);
Add missing header to fix this error.
