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.

Thanks to Terry Wu <terrywu2009@gmail.com> for pointing this issue and
to Andy Walls <awalls@radix.net> for an initial patch for this fix.

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.

dvb_dvr_read may unlock the dmxdev mutex and return -ENODEV, except this
function is a file op and will never be called with the mutex held.

There's existing mutex_lock and mutex_unlock around the actual read but
it's commented out.  These should probably be uncommented but the read
blocks and this could block another non-blocking reader on the mutex
instead.

This change comments out the extra mutex_unlock.

Change kmalloc()/kfree() to vmalloc()/vfree() for sglist allocation
during videobuf_dma_map() and videobuf_dma_unmap()

High resolution sensors might require too many contiguous pages
to be allocated for sglist by kmalloc() during videobuf_dma_map()
(i.e. 256Kib for 8MP sensor).
In such situations, kmalloc() could face some problem to find the
required free memory. vmalloc() is a safer solution instead, as the
allocated memory does not need to be contiguous.

Most UVC camera include an interrupt endpoint to report control value changes,
video streaming errors and camera button events. The USB controller
continuously polls the interrupt endpoint to retrieve such events. This
prevents the device from being auto-suspended, and thus consumes power.

Reporting video streaming errors don't make sense when the V4L2 device is
closed. Control value changes are probably useless as well if nobody listens to
the events, although caching will probably have to be completely disabled then.
No polling is thus be required when /dev/videoX is not opened.

To enable auto-suspend and save power do not poll the interrupt endpoint until
the device is open. We lose the ability to detect button events if no
application is using the camera.
