Subject: pps: claim parallel port exclusively
From: Alexander Gordeev <lasaine@lvk.cs.msu.su>

Both pps_parport and pps_gen_parport are written in a way that they can't
share a port with any other driver.  This can result in locking up the
process that loads modules or even the whole kernel if the modules are
compiled in.  Use PARPORT_FLAG_EXCL to indicate this.
