c6604150ab V4L/DVB (5716): Tda10086,tda826x: fix tuning, STR/SNR values
Several people reported unreliable reception with the current driver.
Furthermore, STR and SNR values seem to be inverted.
This fix is based on a patch posted by Hartmut Hackman.
Thanks to Helmut Auer for testing and helping to optimize the patch.
tda826x:
- set baseband cut-off to 19 MHz
tda10086:
- change the parameters of the carrier recovery loop
- toggle register 0x02 between 0x35 (tuning) and 0x00 (locked)
- invert STR and SNR values

e4a49d76ca V4L/DVB (4428): Fix tda826x detection
The tda826x detection was (correctly) cleaned up earlier, but unfortunately
changing the number of received i2c messages from 2 -> 1 was missed. This
fixes it.

8b9a46647b V4L/DVB (4403): Use dprintk in tda826x.
As opposed to printk() at the moment, which will fill logs uselessly

ef09c071a2 V4L/DVB (4400): Tda826x: Remove 0-byte I2C write; put tuner_ops info in static struct
Remove the 0-byte write that precedes 2-byte read.
Move initialize the info field in the static tuner_ops definition, so
that it doesn't need to be done manually.
