[PATCH 18/19] lib/crypto: gf128hash: Remove unused content from ghash.h

Eric Biggers
2026-03-19T06:19:23Z

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.
