Subject: crypto: sha512_ssse3 - fix byte count to bit count conversion
From: Jussi Kivilinna <jussi.kivilinna@xxxxxx>
commit cfe82d4f45c7cc39332a2be7c4c1d3bf279bbd3d upstream.
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:
