Pull crypto fixes from Herbert Xu:
 "This fixes the following issues:

  API:
   - A large number of bug fixes for the af_alg interface, credit goes
     to Dmitry Vyukov for discovering and reporting these issues.

  Algorithms:
   - sw842 needs to select crc32.
   - The soft dependency on crc32c is now in the correct spot.

  Drivers:
   - The atmel AES driver needs HAS_DMA.
   - The atmel AES driver was a missing break statement, fortunately
     it's only a debug function.
   - A number of bug fixes for the Intel qat driver"
