[PATCH] crypto: talitos - Fix sparse warnings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The talitos driver has a large number of sparse warnings.  It appears
to have only been tested on big-endian and where cpu_to_be32 is a
no-op.  This patch tries to sort out the confusion around the __be32
descriptors and removes bogus cpu_to_be32 conversions on the constants.
