[PATCH] better CONFIG_W1_SLAVE_DS2433_CRC handling
CONFIG_W1_SLAVE_DS2433_CRC can be used directly, there's no reason for the indirection of defining a different variable in the Makefile. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Evgeniy Polyakov <johnpol@2ka.mipt.ru> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
