From: Hans Verkuil <[email protected]>
- Adds missing msp34xxg_reset to VIDIOC_S_STD (just like VIDIOCSCHAN).
- Improves msp3400 debug messages.
Now, all kernel message in msp3400.c use the same prefix
and include the I2C bus to differentiate between multiple
msp3400 I2C chips.
- Correctly prints the chip identifier for the msp44xx chips.
- msp34xxg cleanups.
