Commit e1324ece2af4 ("ARM: imx: Remove i.MX35 board files") removes the config MACH_MX35_3DS in arch/arm/mach-imx/Kconfig. Hence, since then, the MX35 3DS BOARD MC9S08DZ60 GPIO functions are dead code as its config GPIO_MC9S08DZ60 depends on the config MACH_MX35_3DS. Luckily, ./scripts/checkkconfigsymbols.py warns on non-existing configs: MACH_MX35_3DS Referencing files: drivers/gpio/Kconfig Remove the obsolete MX35 3DS BOARD MC9S08DZ60 GPIO functions.
