V4L/DVB (9570): uvcvideo: Handle failed video GET_{MIN|MAX|DEF} requests more gracefully
Failed requests will now generate a one-time warning message instead of the
usual "Failed to query..." error, which should be more user-friendly. The
driver will also recover automatically from failed GET_MIN/GET_MAX requests
when the device is half-broken without requiring the MINMAX quirk (fully
broken devices still need the quirk).

suspending of module if usb_autosuspend enabled.
V4L/DVB (9569): uvcvideo: Sort the frame descriptors during parsing
The UVC specification does not require frame descriptors to be sorted by
bFrameIndex. At least one camera (145f:013e) is known not to sort the
descriptors properly, so they need to be sorted during parsing as the driver
then accesses them by index.
V4L/DVB (9536): WinFast DTV2000 H: add support for missing analog inputs
Add support for the following inputs:
- radio tuner
- composite 1 & 2 (only 1 is physically available, but composite 2 is also
advertised by windows driver)
- svideo

This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".
To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.
We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.
We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.
