[PATCH] drivers/isdn/sc/: possible cleanups
This patch contains the following possible cleanips: - make some needlessly global code static - remove the compiled but completely unused debug.c - remove or #if 0 the following unused global functions: - command.c: loopback - command.c: loadproc - init.c: irq_supported - packet.c: print_skb - shmem.c: memset_shmem - timer.c: trace_timer Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
