commit 15fd2566bf54ee4d4781d8f170acfc9472a1541f upstream.
The PM code was racy, possibly causing the driver to submit
requests to a powered down device. Fix the race and while
at it simplify the PM code.

when backlog was consumed causing a memory leak when backlog is
used.

ccree had a mechanism for IV generation which was not compatible
with the Linux seqiv or echainiv iv generator and was never used
in any of the upstream versions so drop all the code implementing it.

crypto: ccree - fix backlog notifications2019-04-25T07:38:14+00:00Gilad Ben-Yossefgilad@benyossef.com2019-04-18T13:38:46+00:00urn:sha1:a108f9311c01271bccad45d321cf9ddfac852c4b
We were doing backlog notification callbacks via a cipher/hash/aead
request structure cast to the base structure, which may or may not
work based on how the structure is laid in memory and is not safe.
Fix it by delegating the backlog notification to the appropriate
internal callbacks which are type aware.
