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
