    Subject[PATCH 2/3] amd64_edac: fix ecc_enable_override handling
    Date
    amd64_check_ecc_enabled() returns non-zero status when ECC
    checking/correcting is disabled and this fails further loading of the
    driver even when 'ecc_enable_override' module param is used.

    Fix that by clearing return status in that case.
