TTY: serialP, remove unused material
First, remove unused macro and rs_multiport_struct structure. Nobody uses them at all. Further, the 2 drivers (they are below) which use the rest of structures from serialP.h (async_struct and serial_state) do not use all the members. Remove the members: * which are unused or * which are only initialized and never used for something real. Everybody should avoid the structures with a looong distance. Finally, remove the ALPHA kludge MCR quirks. They are 1:1 copy from 8250.h. No need to redefine them here. The 2 promised users of the structures: arch/ia64/hp/sim/simserial.c drivers/tty/amiserial.c Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Tony Luck <tony.luck@intel.com> Cc: Fenghua Yu <fenghua.yu@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
