Ingo Schneider afa47abf09 V4L/DVB (3669): Configurable dma buffer size for saa7146-based budget dvb cards
- Issue a warning when more than 80% of the DMA buffer is being used 
  (probably due to bad IRQ latency). Warnings are rate-limited.
- Introduce a new parameter 'bufsize' (in KByte) which increases the
  default DMA buffer of 188 KByte up to 1410 KByte (Activy: 564 KByte).
