this patch adds a new driver for the Silicon Labs Si470x FM Radio Receiver. It
should also work for the identical ADS/Tech FM Radio Receiver (formerly
Instant FM Music) as soon as I find out the USB Vendor and Product ID.
The driver is inspired by several other USB and radio drivers, but mainly from
the D-Link DSB-R100 USB radio (dsbr100.c).
The USB stick currently has an Si4701 FM RDS radio receiver. But the other
Si470x devices are pin and register compatible, so that in the future the
driver can easily be patched to support these too. Therefore I named the
driver radio-si470x and the configuration option usb-si470x.
The driver itself just provides the control function over the radio. For
getting audio back, the device support the USB audio class, which is
implemented in the already existing driver.
I tested the driver in the last days, until it now satisfies all my
functionality and robustness requirements. The application I used for testing
was kradio.

The file drivers/media/video/videodev.c defines both video_device_alloc and
video_device_release. These are essentially just kzmalloc and kfree,
respectively, but it seems better to use video_device_release, as done in
the other media files, rather than kfree, in case the implementation some
day changes.

Video_device_alloc returns the result of a kzalloc. In this case, the
value is stored in a local variable which is not copied elsewhere before
the point of the error return (video_register_device does not save its
first argument anywhere if it returns a negative value). Thus, a
video_device_release it needed before the error return.

I've tested with other ATSC tuners just to confirm, using:
us-ATSC-center-frequencies-8VSB
Anyhow, as it turns out, the tuner-xc2028 *does* require a tuning offset
for ATSC. Even though the linux-dvb api passes in center frequencies
from userspace, apparantly the xceive firmware is already factoring in
the tuning offset to center.

If we switch to DTV78 firmware when we detect this condition, we can
avoid firmware reloads when switching between VHF and UHF transponders.
Place the state for this in the control structure so that card drivers
can hint to us to use DTV78 firmware from the first tuning attempt.

We have been inserting a mystery 500kHz offset for tuning 7MHz channels,
however some experimentation reveals it is only needed under certain
conditions with specific firmware combinations. Document these and only
apply the offset when we know it is required.

When searching for the right S-Code table to load, check the HAS_IF flag
against the firmware we are checking instead of against the the "type"
requested. We already ignore the scode type requested if the caller passed
an int_freq; this makes the search by frequency consistent with that behaviour.

Don't modify the control structure that was provided at attach when applying
an offset to the S-Code, otherwise it will be incorrect on subsequent tunes.

Add "int_freq" to the debugging output when selecting firmware and the
HAS_IF flag when dumping firmware during load.

The patch below adds the "Pinnacle Dazzle DVC 100" to the list of
cards supported by the em28xx driver. As the configuration is the same
as the DVC 90 one, it simply adds a new USB ID to the list of devices
supported by the DVC 90 configuration.
