17b27478cc [media] s5p-tv: hdmi: use DVI mode
Current version of the driver does not support HDMI features
not present in DVI standard. Therefore DVI mode is used to
keep compatibility with DVI devices.

778f295080 [media] em28xx: replug locking cleanup
Simplifies the locking by moving the em28xx_init_extension() call until
em28xx_usb_probe() has finished with the dev->lock mutex. It therefore
makes the second and subsequent "plugging" events logically identical to
the first "plugging" event when the em28xx-dvb and em28xx-alsa modules
must be loaded (i.e. registered).

Basically, em28xx_usb_probe() requests that em28xx-dvb be loaded and
also triggers udev to initialise the V4L2 devices. These two events are
serialised by the dev->lock mutex but the order that they happen in is
undefined. But this has always been the case anyway.

b868a537b6 [media] em28xx: fix deadlock when unplugging and replugging a DVB adapter
This fixes the deadlock that occurs with either multiple PCTV 290e adapters or when a single PCTV 290e adapter is replugged.

For DVB devices, the device lock must now *not* be held when adding/removing either a device or an extension to the respective lists. (Because em28xx_init_dvb() will want to take the lock instead).

Conversely, for Audio-Only devices, the device lock *must* be held when adding/removing either a device or an extension to the respective lists.

d7222e7d6f [media] em28xx: fix race on disconnect
This patch closes the race on the device and extension lists at USB disconnect
time. Previously, the device was removed from the device list during
em28xx_release_resources(), and then passed to the em28xx_close_extension()
function so that all extensions could run their fini() operations. However, this
left a (brief, theoretical, highly unlikely ;-)) window between these two calls
during which a new module could call em28xx_register_extension(). The result
would have been that the em28xx_usb_disconnect() function would also have passed
the device to the new extension's fini() function, despite never having called
the extension's init() function.

This patch also restores em28xx_close_extension()'s symmetry with
em28xx_init_extension(), and establishes the property that every device in the
device list must have been initialised for every extension in the extension list.

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

3e0ac6717b [media] media: Fix a UVC performance problem on systems with non-coherent DMA
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.

For uvc device, dev->vdev.dev is the &intf->dev,
uvc_delete code is as below:
	usb_put_intf(dev->intf);
	usb_put_dev(dev->udev);

	uvc_status_cleanup(dev);
	uvc_ctrl_cleanup_device(dev);

	if (dev->vdev.dev)
		v4l2_device_unregister(&dev->vdev);

Fix it by get_device in v4l2_device_register and put_device in v4l2_device_disconnect

0a54b86a71 [media] mt9t001: Aptina (Micron) MT9T001 3MP sensor driver
The MT9T001 is a parallel 3MP sensor from Aptina (formerly Micron)
controlled through I2C.

The driver creates a V4L2 subdevice. It currently supports binning and
cropping, and the gain, exposure, test pattern and black level controls.

5b6c3ef0e4 [media] omap3isp: video: Avoid crashes when pipeline set stream operation fails
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.

c62e2a19d2 [media] omap3isp: Don't fail streamon when the sensor doesn't implement s_stream
The code handles subdevs with no s_stream operation correctly, but
returns -ENOIOCTLCMD by mistake if the first subdev in the chain has no
s_stream operation. Return 0 in that case.

6426e14a7e [media] noon010pc30: Conversion to the media controller API
Replace g/s_mbus_fmt ops with the pad level get/set_fmt operations.
Add media entity initialization and set subdev flags so the host driver
creates a subdev device node for the driver.
A mutex was added for serializing the subdev operations. When setting
format is attempted during streaming an (EBUSY) error will be returned.

After the device is powered up it will now remain in "power sleep"
mode until s_stream(1) is called. The "power sleep" mode is used
to suspend/resume frame generation at the sensor's output through
s_stream op.
