    Subject[PATCH 4.19 020/293] crypto: talitos - reduce max key size for SEC1
    Date
    From: Christophe Leroy <christophe.leroy@c-s.fr>

    commit b8fbdc2bc4e71b62646031d5df5f08aafe15d5ad upstream.

    SEC1 doesn't support SHA384/512, so it doesn't require
    longer keys.

    This patch reduces the max key size when the driver
    is built for SEC1 only.

    Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
    Fixes: 03d2c5114c95 ("crypto: talitos - Extend max key length for SHA384/512-HMAC and AEAD")
