    crypto: sun8i-ss - remove unnecessary alignmask for ahashes · 028a1447
    Eric Biggers authored
    The crypto API's support for alignmasks for ahash algorithms is nearly
    useless, as its only effect is to cause the API to align the key and
    result buffers.  The drivers that happen to be specifying an alignmask
    for ahash rarely actually need it.  When they do, it's easily fixable,
    especially considering that these buffers cannot be used for DMA.
    
    In preparation for removing alignmask support from ahash, this patch
    makes the sun8i-ss driver no longer use it.  This driver didn't actually
    rely on it; it only writes to the result buffer in sun8i_ss_hash_run(),
    simply using memcpy().  And sun8i_ss_hmac_setkey() does not assume any
    alignment for the key buffer.
