b3944c8f67 [media] em28xx: rename em28xx_hint_sensor() to em28xx_detect_sensor()
Now that the board hints and the sensor initialization/configuration have been
separated, em28xx_detect_sensor() is the better name for this function.

484fbbeb3e [media] em28xx: separate sensor detection and initialization/configuration
Sensor detection and initialization/configuration are currently mixed together.
This works as long as all devices with a particular sensor are working with the
same board configuration. In the long run, this will be not sufficient, so
separate these both steps to make the code more flexible and future proof.
This also makes the code more consistent, because the initialization of the
MT9V011 sensor subdevice is already separated.

2d466e1136 [media] em28xx: fix and separate the board hints for sensor devices
The current board hint code is mixed together with the sensor detection and
initialization code. It actually selects a board depending on the detected
sensor type only, with the result that 3 of the 6 webcam boards are currently
dead.
Separate it and move it to em28xx_hint_board() which already contains the board
hints for analog capturing+TV and DVB devices.
This way, we have all board hints at a common place which makes it easier
to extend the code and reduces the risk of regressions.
It also makes it possible again to use the boards EM2750_BOARD_DLCW_130,
EM2820_BOARD_VIDEOLOGY_20K14XUSB and EM2860_BOARD_NETGMBH_CAM (using the module
parameter "card").
NOTE: the current board hint logic for webcams is preserved. Not more not less.

72cc9ba39a [media] em28xx: ignore isoc DVB USB endpoints with wMaxPacketSize = 0 bytes for all alt settings
Some devices without DVB support (such as the "Terratec Grabby" and
"Easycap DC-60") provide isochronous DVB USB endpoints with wMaxPacketSize set
to 0 bytes for all alt settings.
Ignore these endpoints and avoid registering a DVB device node and loading the
DVB driver extension.

a3ea4bf98b [media] em28xx: add support for em25xx i2c bus B read/write/check device operations
The webcam "SpeedLink VAD Laplace" (em2765 + ov2640) uses a special algorithm
for i2c communication with the sensor, which is connected to a second i2c bus.
We don't know yet how to find out which devices support/use it.
It's very likely used by all em25xx and em276x+ bridges.
Tests with other em28xx chips (em2820, em2882/em2883) show, that this
algorithm always succeeds there although no slave device is connected.
The algorithm likely also works for real i2c client devices (OV2640 uses SCCB),
because the Windows driver seems to use it for probing Samsung and Kodak
sensors.

106cf649d0 [media] tuner-core: don't set has_signal/get_afc if not supported
If the tuner frontend does not support get_rf_strength, then don't set
the has_signal callback. Ditto for get_afc.
Both callbacks overwrite the signal and afc fields of struct v4l2_tuner
but that should only happen if the tuner can actually detect this. If
it can't, then it should leave those fields alone so other subdevices
can try and detect the signal/afc.
This fixes the bug where the au8522 detected a signal and then tuner-core
overwrote it with 0 since the xc5000 tuner does not support get_rf_strength.
