Subject: lib/crypto: gf128hash: Remove unused content from ghash.h
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a78ae6e364aea8aec3996de274c4f5bc98e1d771;p=thirdparty%2Fkernel%2Fstable.git

lib/crypto: gf128hash: Remove unused content from ghash.h

Now that the structures in <crypto/ghash.h> are no longer used, remove
them.  Since this leaves <crypto/ghash.h> as just containing constants,
include it from <crypto/gf128hash.h> to deduplicate these definitions.
