    crypto: nx - Check for bogus firmware properties · 8000112c
    Herbert Xu authored
    The nx driver reads two crucial paramters from the firmware for
    each crypto algorithm, the maximum SG list length and byte limit.
    Unfortunately those two parameters may be bogus, or worse they
    may be absent altogether.  When this happens the algorithms will
    still register successfully but will fail when used or tested.
    
    This patch adds checks to report any firmware entries which are
    found to be bogus, and avoid registering algorithms which have
    bogus parameters.  A warning is also printed when an algorithm
    is not registered because of this as there may have been no firmware
    entries for it at all.
