[PATCH] drivers/isdn/i4l/: possible cleanups
This patch contains the following possible cleanups: - make needlessly global code static - remove the following unused global function: - isdn_audio.c: isdn_audio_2adpcm_flush - remove the following unused struct: - isdn_net.c: isdn_concap_demand_dial_dops Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
