From: Julian Braha <julianbraha@xxxxxxxxx> [ Upstream commit 7c36194558cf49a86a53b5f60db8046c5e3013ae ] When RTLLIB_CRYPTO_TKIP is enabled and CRYPTO is disabled, Kbuild gives the following warning: WARNING: unmet direct dependencies detected for CRYPTO_MICHAEL_MIC Depends on [n]: CRYPTO [=n] Selected by [m]: - RTLLIB_CRYPTO_TKIP [=m] && STAGING [=y] && RTLLIB [=m] WARNING: unmet direct dependencies detected for CRYPTO_LIB_ARC4 Depends on [n]: CRYPTO [=n] Selected by [m]: - RTLLIB_CRYPTO_TKIP [=m] && STAGING [=y] && RTLLIB [=m] - RTLLIB_CRYPTO_WEP [=m] && STAGING [=y] && RTLLIB [=m] This is because RTLLIB_CRYPTO_TKIP selects CRYPTO_MICHAEL_MIC and CRYPTO_LIB_ARC4, without depending on or selecting CRYPTO, despite those config options being subordinate to CRYPTO.
