The empty line here looks bogus to me.

Good eye.  It's unnecessary.

  Did you re-run checkpatch after

fixing the unnecessary space to see if it still complained about having
a 'blank line after declarations'?

 Yes, it still complains even after fixing unnecessary space.

It's a checkpatch defect.

It's been fixed by:

I'm generally opposed to these sorts of checkpatch patches, especially
when they are just warnings.  It's great for a new driver in the staging
tree, but it makes backporting future bugfixes that much harder when
drivers have been live in mainline.

Blind adherence to checkpatch isn't always a great idea.

But bugfix backports haven't been much of an issue in
other subsystems with fairly active whitespace/style
changes.
