Subject: Re: [PATCH 2/2] backlight: arcxcnn: devicetree bindings for
 ArticSand devices

Your subject should look something like [PATCH vX 0/Y]

Where X is the number of times you've submitted this set.

This is a change log, not a commit log.

Here is where you tell us about the patch.

  Read: Documentation/SubmittingPatches
        Documentation/SubmitChecklist

... before submitting again.

In here (below the ---) you should have a change log which looks like
this:

v3 => v4:
- The changes you made

v2 => v3:
- The changes you made

v1 => v2:
- The changes you made

... etc
