patch by Adrian Bunk:

This patch contains the following possible cleanups:
- make needlessly global code static
- remove the following EXPORT_SYMBOL'ed but unused function:
  - bt8xx/bt878.c: bt878_find_by_i2c_adap
- remove the following unused global functions:
  - dvb-core/dvb_demux.c: dmx_get_demuxes
  - dvb-core/dvb_demux.c: dvb_set_crc32
- 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
