This patch is adapted from a patch from Sarah Sharp (2010/05/03).
The xHCD handler checks the USB bandwidth on usb_set_interface()
instead of on usb_submit_urb().
Now, the same treatment is applied in case of error of both functions.

Previously image transfer used to use the highest altsetting, which, most of
the time, took the whole USB bandwidth.
Now, the altsetting is chosen according to an estimation of the bandwidth
needed for image transfer.

This is an improved version of the patch I sent a little ago.
The problem was:
On my DC-1125 webcam chip from Syntek, whenever the webcam turns
on, the LED light on it is turned on also and never turns off again unless
system is shut downed or restarted.
The previous version seemed to break some other laptop webcam work. Thanks
to Andrea Anacleto for the bug report and solution.

VIDIOC_DBG_S_REGISTER
Ioctls on the subdevs node currently don't dispatch the register access debug
driver callbacks. Add the dispatching with the same security checks are for
non subdev video nodes (i.e. only capable(CAP_SYS_ADMIN may call the register
access ioctls).

The UVC driver uses usb_alloc_coherent() to allocate DMA data buffers.
On systems without coherent DMA this ends up allocating buffers in
uncached memory. The subsequent memcpy's done to coalesce the DMA
chunks into contiguous buffers then run VERY slowly. On a MIPS test
system the memcpy is about 200 times slower. This issue prevents the
system from keeping up with 720p YUYV data at 10fps.
The following patch uses kmalloc to alloc the DMA buffers instead of
usb_alloc_coherent on systems without coherent DMA. With this patch
the system was easily able to keep up with 720p at 10fps.

If streaming can't be enabled on the pipeline, the DMA buffers queue is
not emptied. If the buffers then get freed the queue will end up
referencing free memory. This is usually not an issue, as the DMA queue
will be reinitialized the next time streaming is enabled, before
enabling the hardware.
However, if the sensor connected at the pipeline input is free-running,
the CCDC will start generating interrupts as soon as it gets powered up,
before the streaming gets enabled on the hardware. This will make the
CCDC interrupt handler access freed memory, causing a crash.
Reinitialize the DMA buffers queue in isp_video_streamon() if the error
path to make sure this situation won't happen.

The imon devices have either 1 or 2 usb interfaces on them, each wired
up to its own urb callback. The interface 0 urb callback is wired up
before the imon context's rc_dev pointer is filled in, which is
necessary for imon 0xffdc device auto-detection to work properly, but we
need to make sure we don't actually run the callback routines until
we've entirely filled in the necessary bits for each given interface,
lest we wind up oopsing. Technically, any imon device could have hit
this, but the issue is exacerbated on the 0xffdc devices, which send a
constant stream of interrupts, even when they have no valid key data.

The following patch provides wider carrier search.
As with existing code search starts at MSB aligned. The boundary
is widened to start at -9. In order to save time, if no carrier is
detected at the start it advances to the next alignment until carrier
is found.
The stv0288 will detect a DVB-S2 carrier on all steps , a
time out of 11 steps is introduced to drop out of the loop.
In stv0288_set_symbol carrier and timing loops are restored to
default values (inittab) before setting the symbol rate on each tune. A
slight drift was noticed with full scan in the higher IF frequencies of
each band.
