29b05e22f5 [media] em28xx: use usb_interface for dev_foo() calls
The usb_device->dev is not the right device for dev_foo() calls.
Instead, it should use usb_interface->dev.

f51e80804f [media] cec: pass parent device in register(), not allocate()
The cec_allocate_adapter function doesn't need the parent device, only the
cec_register_adapter function needs it.

Drop the cec_devnode parent field, since devnode.dev.parent can be used
instead.

This change makes the framework consistent with other frameworks where the
parent device is not used until the device is registered.

190b23b4eb [media] em28xx: only use mt9v011 if camera support is enabled
In randconfig builds that select VIDEO_EM28XX_V4L2 and
MEDIA_SUBDRV_AUTOSELECT, but not MEDIA_CAMERA_SUPPORT, we get
a Kconfig warning:

 warning: (VIDEO_EM28XX_V4L2) selects VIDEO_MT9V011 which has unmet direct dependencies (MEDIA_SUPPORT && I2C && VIDEO_V4L2 && MEDIA_CAMERA_SUPPORT)

This avoids the warning by making that 'select' conditional on
MEDIA_CAMERA_SUPPORT. Alternatively we could mark EM28XX as
'depends on MEDIA_CAMERA_SUPPORT', but it does not seem to
have any real dependency on that itself.

fa6317eedd [media] go7007: add MEDIA_CAMERA_SUPPORT dependency
If MEDIA_SUBDRV_AUTOSELECT and VIDEO_GO7007 are both set, we
automatically select VIDEO_OV7640, but that depends on MEDIA_CAMERA_SUPPORT,
so we get a Kconfig warning if that is disabled:

warning: (VIDEO_GO7007) selects VIDEO_OV7640 which has unmet direct dependencies (MEDIA_SUPPORT && I2C && VIDEO_V4L2 && MEDIA_CAMERA_SUPPORT)

This adds another dependency so we don't accidentally select
it when it is unavailable.

The Rift CV1 Sensor has bInterfaceClass set to vendor specific, so we
need an entry in uvc_ids to probe it. Just as the Rift DK2 IR tracker,
it misreports the pixel format as YUYV instead of Y8.

The sensor is configured with a low exposure time and high black level
by default, so that only bright IR sources can be seen.

modified by Hans Verkuil and then seemingly forgotten before changes
suggested by Keith Pyle here:

http://www.mail-archive.com/linux-media@vger.kernel.org/msg75163.html

were made and tested.

I have implemented the suggested changes and have been testing for the
last 2 months. I am no longer experiencing lockups while recording
(with blue light on, requiring power cycling) which had been a long
standing problem with the HD-PVR. I have not noticed any other problems

1596c387e9 gp8psk: fix gp8psk_usb_in_op() logic
Commit bc29131ecb10 ("[media] gp8psk: don't do DMA on stack") fixed the
usage of DMA on stack, but the memcpy was wrong for gp8psk_usb_in_op().
Fix it.

From Derek's email:
    "Fix confirmed using 2 different Skywalker models with
     HD mpeg4, SD mpeg2."

ba13e98f2c dib0700: fix nec repeat handling
When receiving a nec repeat, ensure the correct scancode is repeated
rather than a random value from the stack.  This removes the need for
the bogus uninitialized_var() and also fixes the warnings:

    drivers/media/usb/dvb-usb/dib0700_core.c: In function ‘dib0700_rc_urb_completion’:
    drivers/media/usb/dvb-usb/dib0700_core.c:679: warning: ‘protocol’ may be used uninitialized in this function

[sean addon: So after writing the patch and submitting it, I've bought the
             hardware on ebay. Without this patch you get random scancodes
             on nec repeats, which the patch indeed fixes.]

e950267ab8 [media] uvcvideo: uvc_scan_fallback() for webcams with broken chain
Some devices have invalid baSourceID references, causing uvc_scan_chain()
to fail, but if we just take the entities we can find and put them
together in the most sensible chain we can think of, turns out they do
work anyway. Note: This heuristic assumes there is a single chain.

At the time of writing, devices known to have such a broken chain are
  - Acer Integrated Camera (5986:055a)
  - Realtek rtl157a7 (0bda:57a7)

3a611875d9 [media] zr364xx: 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.

adjusted if needed.

67390d21fe [media] siano: 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.

	if ($next ne "") {
		$c=$_;

			$next =~ s/\"\n$//;
			$n = expand($next);
			$funpos = index($n, '(');
