Subject[DVB patch 20/48] cleanups, make stuff static
This patch contains the following possible cleanups:
o make needlessly global code static
o remove the following EXPORT_SYMBOL'ed but unused function:
- bt8xx/bt878.c: bt878_find_by_i2c_adap
o remove the following unused global functions:
- dvb-core/dvb_demux.c: dmx_get_demuxes
- dvb-core/dvb_demux.c: dvb_set_crc32
o remove the following unneeded EXPORT_SYMBOL's:
- dvb-core/dvb_demux.c: dvb_dmx_swfilter_packet
- dvb-core/dvb_demux.c: dvbdmx_connect_frontend
- dvb-core/dvb_demux.c: dvbdmx_disconnect_frontend
- dvb-core/dvbdev.c: dvb_class
