Ok, so there is some improvement [copy-pasted commit log->commit log for
the actual change] in commit log but there are some typos as well. Also,
like all other your previous patches subject line is missing some words.

For the commit log, subject line and patch version related things check
Documentation/SubmittingPatches .

Like mentioned by Laura in previous version of the patch, you are not
supposed to send this patch in the kernel now. You can send the part of
a patch [may be ion_handle_put_nolock one] if it will apply after her
patches for the ion_phys.

Also, for this patch Joe's compile-testing and unused variable related
warning suggestion still applies. Please compile-test any patch before
sending it in to the mainline.
