I think this patch is still correct. Defining DEBUG makes sense to
enable dev_dbg() messages. CONFIG_DEBUG_GPIO is used by one driver to
enable code that can lead to undefined behavior (should it maybe be
#if 0?). So the Makefile bit and the Kconfig option can stay but I'd
love to see extra_checks gone.
