This is not a good way to make the change.  Put le16_to_cpu in front of
its argument list and move the indentation back to some multiple of tabs
if needed.

This is not the right starting point.  It is on top of on of your
incorrect patches.  Overall, I think you have done something wrong in
redoing this series.

You forgot a ":" after "greybus" on most of the subject lines in this
patch series :(

Please fix up and resend the whole thing.

You can see the missed ":" very easily here.  It's a good check to
verify that you got the text correct to look at this output.
