I think doing just this spelling and get/set correction and
fixing the alignment in this single case in a single patch
would be fine here.

Foxing the alignment for the entire file would be a more
significant change and isn't necessary in this patch.

Another thing possible for the file would be to change the
mfc_debug and mfc_err/mfc_info macros to use pr_<level>
without the generally unnecessary __func__ and __LINE__
uses.

This could both enable dynamic_debug uses for the KERN_DEBUG
cases and reduce overall object size.
