Adrian Bunk 7665a08928 [PATCH] drivers/net/wan/: possible cleanups 
This patch contains possible cleanups including the following:
- make needlessly global code static
- #if 0 the following unused global function:
  - sdladrv.c: sdla_intde
- remove the following unused global variable:
  - lmc_media.c: lmc_t1_cables
- remove the following unneeded EXPORT_SYMBOL's:
  - cycx_drv.c: cycx_inten
  - sdladrv.c: sdla_inten
  - sdladrv.c: sdla_intde
  - sdladrv.c: sdla_intack
  - sdladrv.c: sdla_intr
  - syncppp.c: sppp_input
  - syncppp.c: sppp_change_mtu
