As you are already in a tasklet, it is unnecessary to call spin_lock_bh.

FWIW you should put spaces after the colons.  It's generally a good
practice to look at the prefix previous authors used for a given piece
of code with 

git log -- $file_path

This would be a better subject:

nfp: replace spin_lock_bh with spin_lock in tasklet callback
