Reviewed-by: Jarkko Sakkinen <jarkko.sakki...@linux.intel.cm> For rest of the patches I'll look at them post-v4.5. I'm still waiting for my first pull request containing fixes for that release to be taken. James, would it be possible to take the pull request containing fixes soon that I origianally sent already in Jan and bit updated version few days ago [1]? I still have one more pull request coming after that. It will contain only few line changes: * Missing put_device() in two places. * There is a small change to ABI behavior (I'll post it soon) of policy sealing so I really need it for this release because 4.5 is the first release containing this feature and I cannot change it when the release is tagged. Thank you.
