3.5.7.22 -stable review patch.  If anyone has any objections, please let me know.

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

From: Dan Carpenter <dan.carpenter@oracle.com>

commit d0bd9a41186e076ea543c397ad8a67a6cf604b55 upstream.

The write_parport_reg_nonblock() function shouldn't sleep because it's
called with spinlocks held.
