[PATCH v2 0/4] Convert greybus loopback to core async API

[Bryan O'Donoghue]

v2:
- Added Reviewed-by Johan for patch #3
- Added fix for mutex hold duration.
  Johan mentioned the holding of this across a gb_operation_send() call.
  Looking at this it shows a bug that crept in between two commits detailed
  in patch#1 here.
- Split a separate bugfix from Mitch which had been squashed into an old
  patch from nearly a year ago
- Added Mitch to the cc list
- Depends on Arnd Bermann's patch
  "staging: greybus/loopback: use ktime_get() for time intervals"

v1:
dbec27298b0d ('staging: greybus: operation: add generic timeout support')
gives the ability to remove lots of the asynchronous operation code in
loopback.

Kees is also doing a cleanup of timer code which for loopback will go away
when converting to the core API.

These two patches kill two birds with err, two stones (no aggression to
birds intended) namely:

- Converting over to the core asynchronous API
- Getting rid of the timer code in loopback which will unblock what Kees is
  doing.

Bryan O'Donoghue (4):
  staging: greybus: loopback: Hold per-connection mutex across
    operations
  staging: greybus: loopback: Fix iteration count on async path
  staging: greybus: operation: add private data with get/set accessors
  staging: greybus: loopback: convert loopback to use generic async
    operations
