The VID_A_GPCNT register is for video, not vbi. Read from the right
register and don't write to the video register.
Based upon Devin's initial patch made for an older kernel which I
cleaned up and rebased. Thanks to Kernel Labs for that work.

This is necessary since the *_std_setup functions rely on a valid state->std
field.
Also fix the cx23888_std_setup() to test for 60Hz instead of NTSC, just like
cx25840_std_setup() does.

For those two devices the code wrote to addresses 0x115/6, but on
those devices those addresses have nothing to do with power controls.
So clearly this never worked. Rather than writing to bogus addresses,
just do nothing for the cx2388x and cx231xx.

The cx23888 reports a slightly different Vsrc value than the other

The cx23888 also moves the following registers around:
!cx23888 cx23888
-------- -------
0x418, 0x41c 0x434, 0x438
0x420 0x418 (expect for bit 29 which has a different meaning)
0x478 0x454
Also drop the set_input code where the scaler is changed: this does not
belong here, changing the input should not change the scaler.
And that's besides the fact that that code is plain wrong.
After this change the cx23888 behaves much better. In particular, calling
set_input no longer changes the saturation to 0, causing a grayscale
image.

The cx23888 has the VBI registers at different addresses compared to

While testing the cx23885 driver with various TV standards I found
a number of bugs:
1) norm_maxw() returned 768 instead of 720 for PAL formats. This should
always be 720, so drop this inline function and just always use 720.
2) cropcap() was missing, so the pixelaspect was never known and qv4l2 would
scale the image incorrectly. Add cropcap support.
3) cx23885_set_tvnorm() should just return 0 if the same standard was
set again. If another standard is set, then reset the width/height and
call set_fmt for the subdevs.

Calling synchronize_irq() right before free_irq() is quite useless. On one
hand the IRQ can easily fire again before free_irq() is entered, on the
other hand free_irq() itself calls synchronize_irq() internally (in a race
condition free way), before any state associated with the IRQ is freed.
Patch was generated using the following semantic patch:
// <smpl>

expression irq;

-synchronize_irq(irq);

As pointed by Laurent Navet:
"Calling ktime_add_us() seems useless as is only useful
for it's return value which is ignored."
That's reported by coverity CID 1309761.
Laurent proposed to just remove ktime_add_us, but the fact is that
the logic of this function is broken. Instead, we need to use the
value of the timeout, and ensure that it will work on the loops
to emulate the legacy DiSEqC ioctl (FE_DISHNETWORK_SEND_LEGACY_CMD).
Please notice that the logic was also broken if, for any reason,
msleep() would sleep a little less than what it was expected, as
newdelta would be smaller than delta, and udelay() would not be called.
It should also be noticed that nobody noticed that trouble before
likely because the FE_DISHNETWORK_SEND_LEGACY_CMD is not used
anymore by modern DVB applications.

UVC 1.5 devices report a bInterfaceProtocol value set to 1 in their
interface descriptors. The uvcvideo driver only matches on
bInterfaceProtocol 0, preventing those devices from being detected.
More changes to the driver are needed for full UVC 1.5 compatibility.
However, at least the UVC 1.5 Microsoft Surface Pro 3 cameras have been
reported to work out of the box with the driver with an updated match
table.
Enable UVC 1.5 support in the match table to support the devices that
can work with the current driver implementation. Devices that can't will
fail, but that's hardly a regression as they're currently not detected
at all anyway.
