Hi Darren,

Thank you for your reviews.

I wanted to take update from your update git, to align the patches with series
you pushed to review-dvhart-mellanox-v10.
But I have some issue with 
cda61cd592ebc9534b9786c337b124a86a6e303f hash:
git remote update
Fetching origin
remote: error: inflate: data stream error (incorrect header check)
remote: error: unable to unpack cda61cd592ebc9534b9786c337b124a86a6e303f header
remote: fatal: loose object cda61cd592ebc9534b9786c337b124a86a6e303f (stored in ./objects/cd/a61cd592ebc9534b9786c337b124a86a6e303f) is corrupt
remote: aborting due to possible repository corruption on the remote side.
fatal: protocol error: bad pack header
error: Could not fetch origin

Same in case I just clone git anew.

I am about to re-send the series started from the patch 2.
I currently dropped the changes related to removing dev_err (from FIXME
platform/mellanox: Remove redundant dev_err messa).
I also added one extra patch between
platform/mellanox: mlxreg-hotplug: Modify to use a 
and
platform/mellanox: mlxreg-hotplug: Enable building

And I'll not resend 
platform/x86: mlx-platform: Allow compilation for 32
since it has been moved from the series  as a separate patch.
