Fix a bug in get_index that was introduced earlier.
Also fix two error handling lock-ups in videodev and cx18 that
where found thanks to that bug.

Instead of letting VIDEO_IR_I2C to be selected by VIDEO_IR, if I2C, convert it
into a symbol that depends on both VIDEO_IR and I2C.

Currently, saa7134 is dependent of ir-kbd-i2c, since it uses a symbol that is
defined there. However, as this symbol is used only on saa7134, there's no
sense on keeping it defined there (or on ir-commons).

So, let's move it to saa7134 and remove one symbol for being exported.

Use Hans Verkuil's suggested method of implementing get_index which doesn't
depend on class_for_each_device and instead uses the video_device array. This
simplifies the code and reduces its memory footprint.

Having an _auto suffix is less ambiguous than a 'saa711x' identifier.
It's also used like this in the saa7127 driver.

Thanks to Jean Delvare for suggesting this.

The saa7127 driver supports all of SAA7126, SAA7127, SAA7128 and
SAA1729 devices. Declare all these devices, so that board drivers can
tell which device is present, instead of always relying on
auto-detection (which needs to write to the chip, eek!).

We still need the detection for ivtv, so a special device name
"saa7127_auto" can be used when the caller doesn't know exactly which
device is present.

Same issue as for cx25840: this function sets up the standard timings

For several MPEG controls and the volume control the default as returned
by VIDIOC_QUERYCTRL was incorrect and did not match the actual initial

This is now fixed for cx18 and ivtv.

cx25840_vbi_setup has nothing to do with setting up VBI, but everything

The sn9c102 driver claims to support usb-ID 0x0c45:0x6011, which is
a sn9c102 with ov6650 sensor, but the sn9c102 driver does not support the
ov6650 sensor (tested). Also the sn9c102 driver claims to support usb-ID
0x0c45:0x603f, which is a sn9c102 with CISVF10 sensor, but the sn9c102
driver does not support the CISVF10 sensor (not tested).
