Based on the posting date this series looks like v3.

You should add the version prefix to the patches next time.
e.g. [PATCH v4 ...]

It is also recommended to add a Change-log in the cover letter
explaining what changes were made in each revision.

There are a bunch of checkpatch warnings in this series.
You can use ./scripts/checkpatch.pl on the patches and fix the
issues.
