With ARCH=arm, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in lib/crypto/libsha256.o

Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().

This includes sha1.c and utils.c which, although they did not produce
a warning with the arm allmodconfig configuration, may cause this
warning with other configurations.
