CONFIG_BASE_FULL is equivalent to !CONFIG_BASE_SMALL and is enabled by default: CONFIG_BASE_SMALL is the special case to take care of. So, remove CONFIG_BASE_FULL and move the config choice to CONFIG_BASE_SMALL (which defaults to 'n') Signed-off-by: Yoann Congal <yoann.congal@smile.fr> --- v3->v4: * Split "switch CONFIG_BASE_SMALL to bool" and "Remove the redundant config" (this patch) into two patches * keep CONFIG_BASE_SMALL instead of CONFIG_BASE_FULL --- init/Kconfig | 13 ++++--------- 1 file changed, 4 insertions(+), 9 deletions(-)
