[PATCH] AIRO{,_CS} <-> CRYPTO fixes
CRYPTO is a helper variable, and to make it easier for users, it should therefore select'ed and not be listed in the dependencies. drivers/net/wireless/airo.c requires CONFIG_CRYPTO for compilations. Therefore, AIRO_CS also has to CRYPTO. Additionally, this patch removes the #ifdef's for the non-compiling CRYPTO=n case from drivers/net/wireless/airo.c.
