Subject: [PATCH 3.16 04/99] padata: Remove unused but set variables

3.16.84-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Tobias Klauser <tklauser@...tanz.ch>

commit 119a0798dc42ed4c4f96d39b8b676efcea73aec6 upstream.

Remove the unused but set variable pinst in padata_parallel_worker to
fix the following warning when building with 'W=1':

  kernel/padata.c: In function ‘padata_parallel_worker’:
  kernel/padata.c:68:26: warning: variable ‘pinst’ set but not used [-Wunused-but-set-variable]

Also remove the now unused variable pd which is only used to set pinst.
