- Removal of dead code

Gilad Ben-Yossef (12):
  staging: ccree: correct coding style violations
  staging: ccree: move to kernel bitfields/bitops
  staging: ccree: remove 48 bit dma addr sim
  staging: ccree: cleanup lli access macro
  staging: ccree: remove cycle count debug support
  staging: ccree: move request_mgr to generic bitfield ops
  staging: ccree remove custom bitfield macros
  staging: ccree: remove unused struct
  staging: ccree: use snake_case for hash enums
  staging: ccree: drop no longer used macro
  staging: ccree: remove dead code
  staging: ccree: whitespace fixes

My description of the patch is at fault. This patch gets rid of one
group of these
custom bit field ops users - and so does each one in the rest of the
series until
the patch that deletes them.

Getting rid of the custom bitfield ops was the reason why I've done
it, but of course
as you point it it isn't what the patch is doing. I will fix it.

Thanks. I will fix and resend.
