ni52: clean up initialization of priv
* initialize spinlock once * check586() used to be done before we'd allocated ->priv; these days it's there from the very beginning, so we don't have to play with private copy. Consequently, we don't need to mess with reinitializing ->base, etc. afterwards. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Jeff Garzik <jeff@garzik.org>
