Similar comment to what Fabio made.

But I'll add some formatting comments.

It looks like you have submitted a 2 patch series which fixes all the
checkpatch errors in the vme_user driver?

Kudos for separating out the 2 patches for the 2 different types of
checkpatch errors!  And for submitting a series which fixes the entire
driver!

But you should also include a cover letter for your series.

How are you creating this series?  Are you using 'git format-patch'?
'b4'?  If not using 'b4' I strongly recommend it.[*]

Both of those tools can help with formatting a cover letter and b4 will
help keep track of multiple versions of the series as you fix things.
