[PARISC] Fix mux.c driver
Missing spin_lock_init() made the Mux driver hang on SMP systems. Fix up users of ->hpa to use ->hpa.start instead Remove warning in 8250_gsc.c by eliminating serial_line_nr Signed-off-by: Matthew Wilcox <willy@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
