The USB_DEVICE() list contain some of the product names, but some are missing, and others are different than the message printed during device detection.
Update the comments in order to match what the driver prints.
That makes easier to discover what model matches what physical device.

media: media/usb: set device_caps in struct video_device
Instead of filling in the struct v4l2_capability device_caps field, fill in the struct video_device device_caps field.
That way the V4L2 core knows what the capabilities of the video device are.
But this only really works if all drivers use this, so convert all usb drivers in this patch.

media: usb: pwc: Don't use coherent DMA buffers for ISO transfer
DMA cocherency slows the transfer down on systems without hardware coherent DMA. Instead we use noncocherent DMA memory and explicit sync at data receive handler.
Based on previous commit the following performance benchmarks have been carried out. Average memcpy() data transfer rate (rate) and handler completion time (time) have been measured when running video stream at 640x480 resolution at 10fps.
x86_64 based system (Intel Core i5-3470). This platform has hardware coherent DMA support and proposed change doesn't make big difference here.
* kmalloc: rate = (2.0 +- 0.4) GBps time = (5.0 +- 3.0) usec * usb_alloc_coherent: rate = (3.4 +- 1.2) GBps time = (3.5 +- 3.0) usec
We see that the measurements agree within error ranges in this case. So theoretically predicted performance downgrade cannot be reliably measured here.
armv7l based system (TI AM335x BeagleBone Black @ 300MHz). This platform has no hardware coherent DMA support. DMA coherence is implemented via disabled page caching that slows down memcpy() due to memory controller behaviour.
* kmalloc: rate = ( 94 +- 4) MBps time = (101 +- 4) usec * usb_alloc_coherent: rate = (28.1 +- 0.1) MBps time = (341 +- 2) usec
Note, that quantative difference leads (this commit leads to 3.3 times acceleration) to qualitative behavior change in this case. As it was stated before, the video stream cannot be successfully received at AM335x platforms with MUSB based USB host controller due to performance issues [1].

media: usb: pwc: Introduce TRACE_EVENTs for pwc_isoc_handler()
There were reports that PWC-based webcams don't work at some embedded ARM platforms. [1] Isochronous transfer handler seems to work too long leading to the issues in MUSB USB host subsystem. Also note, that urb->giveback() handlers are still called with disabled interrupts. In order to be able to measure performance of PWC driver, traces are introduced in URB handler section.

[media] pwc: don't break long lines
Due to the 80-cols restrictions, and latter due to checkpatch warnings, several strings were broken into multiple lines. This is not considered a good practice anymore, as it makes harder to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.
The patch was generated via the script below, and manually adjusted if needed.
</script> use Text::Tabs; while (<>) { if ($next ne "") { $c=$_; if ($c =~ /^\s+\"(.*)/) { $c2=$1; $next =~ s/\"\n$//; $n = expand($next); $funpos = index($n, '('); $pos = index($c2, '",'); if ($funpos && $pos > 0) { $s1 = substr $c2, 0, $pos + 2; $s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2; $s2 =~ s/^\s+//;
$s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne "");
print unexpand("$next$s1\n"); print unexpand("$s2\n") if ($s2 ne ""); } else { print "$next$c2\n"; } $next=""; next; } else { print $next; } $next=""; } else { if (m/\"$/) { if (!m/\\n\"$/) { $next=$_; next; } } } print $_; } </script>

[media] vb2: drop v4l2_format argument from queue_setup
The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format.
After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format.
To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s).
