Change order data of buffer in FM simple_tune function. It is usefull for:
1. Set data of tuner with CP bit UP. 0xCE for MK5 or 0xC6 for MK3
2. When call simple_fm_tune, read this byte from config and overwrite
this byte in function simple_radio_bandswitch for set CP bit to OFF.
Of course it can be usefull for other tuner for overwrite default
settings of FM.

Make the KWorld 2800d work properly. In this case, that means making the
profile more generic so that it works for both the Pointnix Intra-Oral USB
camera and the KWorld device.
The device provides the audio through a pass-thru cable, so we don't need
an actual audio capture profile (neither the K-World device nor the Pointnix
have an onboard audio decoder).
Thanks to Paul Thomas for providing sample hardware.

The au0828 basically just doesn't work at 12 Mbps. The isoc pipe needs
nearly 200 Mbps for analog support, so users would see garbage video, and on
the DVB/ATSC side scanning is likely to work but if the user tried to tune it
would certainly appear to have failed.
It's better to fail explicity up front and tell the user to plug into a USB 2.0
port, than to let the driver load and the user have weird problems with tuning
and garbage video.

Both ATSC and DVB @ 6MHz bandwidth require the same offset.
While we're fixing it, let's cleanup the bandwidth setup to better
reflect the fact that it is a function of the bandwidth.

The only two countries that are known to use 6MHz bandwidth are Taiwan
and Uruguay. Both use QAM subcarriers at OFTM.
This patch fixes the firmware load for such countries, where the
required firmware is the QAM one.
This also confirms the previous tests where it was noticed that the 6MHz
QAM firmware doesn't work for cable. So, this patch also removes support
for DVB-C, instead of just printing a warning.

The i2c quirk in the saa7134_i2c_xfer function does a bogus write
to i2c address 0xfd, to work around a bug in the silicon that
affects read transactions.
Unfortunately, this hack is not working properly, since the bogus
write is to 0xfd, an invalid i2c address. Fix this quirk by using
an actual valid i2c address, 0xfe, which is still unlikely to be
used as an i2c address for any actual i2c client.
This is required in order to properly communicate with a TDA10048
DVB-T demod located at i2c address 0x10 on the primary i2c bus.

The code in ir_probe makes the dangerous assumption that all IR
receivers are supported by the driver. The new i2c model makes it
possible for bridge drivers to instantiate IR devices before they are
supported, therefore the ir-kbd-i2c drivers must be made more robust
to not spam the logs or even crash on unsupported IR devices. Simply,
the driver will not bind to the unsupported devices.

Let card drivers probe for IR receiver devices and instantiate them if
found. Ultimately it would be better if we could stop probing
completely, but I suspect this won't be possible for all card types.
There's certainly room for cleanups. For example, some drivers are
sharing I2C adapter IDs, so they also had to share the list of I2C
addresses being probed for an IR receiver. Now that each driver
explicitly says which addresses should be probed, maybe some addresses
can be dropped from some drivers.
Also, the special cases in saa7134-i2c should probably be handled on a
per-board basis. This would be more efficient and less risky than always
probing extra addresses on all boards. I'll give it a try later.
