#     crypto: x86/poly1305 - add back a needed assignment
#     
#     One of the assignments that was removed by commit 4a0c1de64bf9 ("crypto:
#     x86/poly1305 - Remove assignments with no effect") is actually needed,
#     since it affects the return value.
#     
#     This fixes the following crypto self-test failure:
#     
#         alg: shash: poly1305-simd test failed (wrong result) on test vector 2, cfg="init+update+final aligned buffer"
#     
#     Fixes: 4a0c1de64bf9 ("crypto: x86/poly1305 - Remove assignments with no effect")
