crypto: sha512_ssse3 - fix byte count to bit count conversion
Byte-to-bit-count computation is only partly converted to big-endian and is mixing in CPU-endian values. Problem was noticed by sparce with warning: CHECK arch/x86/crypto/sha512_ssse3_glue.c arch/x86/crypto/sha512_ssse3_glue.c:144:19: warning: restricted __be64 degrades to integer arch/x86/crypto/sha512_ssse3_glue.c:144:17: warning: incorrect type in assignment (different base types) arch/x86/crypto/sha512_ssse3_glue.c:144:17: expected restricted __be64 <noident> arch/x86/crypto/sha512_ssse3_glue.c:144:17: got unsigned long long Cc: <stable@vger.kernel.org> Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi> Acked-by: Tim Chen <tim.c.chen@linux.intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
