[PATCHv3 03/11] crypto: omap-sham: implement context export/import APIs

Hmm, looking at the driver, sham_update returns 0 immediately if it
just caches data. In a sense, the update is not completed at this
point. Are you saying this is illegal and can't be done?

Once you call the completion function (and returning zero from
the update itself is equivalent to calling the completion function)
the hardware must not touch the request anymore.

From my understanding, valid results are expected from the driver
only after ->final is called.

That's because you never implemented export/import :)
