gcc warns if prototypes are only visible to the caller but not the callee: crypto/aegis128-neon-inner.c:134:6: warning: no previous prototype for 'crypto_aegis128_init_neon' [-Wmissing-prototypes] crypto/aegis128-neon-inner.c:164:6: warning: no previous prototype for 'crypto_aegis128_update_neon' [-Wmissing-prototypes] crypto/aegis128-neon-inner.c:221:6: warning: no previous prototype for 'crypto_aegis128_encrypt_chunk_neon' [-Wmissing-prototypes] crypto/aegis128-neon-inner.c:270:6: warning: no previous prototype for 'crypto_aegis128_decrypt_chunk_neon' [-Wmissing-prototypes] crypto/aegis128-neon-inner.c:316:5: warning: no previous prototype for 'crypto_aegis128_final_neon' [-Wmissing-prototypes] The prototypes cannot be in the regular aegis.h, as the inner neon code cannot include normal kernel headers. Instead add a new header just for the functions provided by this file. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
