Only the 640x480, 1024x768 and 2592x1944 modes are significantly affected
by the new formula.
In this case, 640x480 and 1024x768 are actually fixed by this change.
Indeed, the sensor was sending data at, for example, 27.33fps instead of
30fps. This is -9%, which is roughly what we're seeing in the array.
Testing these modes with the new clock setup actually fix that error, and
data are now sent at around 30fps.
2592x1944, on the other hand, is probably due to the fact that this mode
can only be used using MIPI-CSI2, in a two lane mode, and never really
tested with a DVP bus.

media: ov5640: Adjust the clock based on the expected rate
The clock structure for the PCLK is quite obscure in the documentation, and
was hardcoded through the bytes array of each and every mode.
This is troublesome, since we cannot adjust it at runtime based on other
parameters (such as the number of bytes per pixel), and we can't support
either framerates that have not been used by the various vendors, since we
don't have the needed initialization sequence.
We can however understand how the clock tree works, and then implement some
functions to derive the various parameters from a given rate. And now that
those parameters are calculated at runtime, we can remove them from the
initialization sequence.
The modes also gained a new parameter which is the clock that they are
running at, from the register writes they were doing, so for now the switch
to the new algorithm should be transparent.

Commit
0185f8501762 ("[media] samples: v4l: from Documentation to
samples directory") moved the v4l2-pci-skeleton driver to the samples
directory. The samples are only be built, if CONFIG_SAMPLES is enabled.
Therefore, VIDEO_PCI_SKELETON is not enough to build the
v4l2-pci-skeleton driver, but SAMPLES needs to be enabled, too. Let
VIDEO_PCI_SKELETON depend on SAMPLES.

media: v4l2-pci-skeleton: replace vb2_buffer with vb2_v4l2_buffer
Commit
2d7007153f0c ("[media] media: videobuf2: Restructure vb2_buffer")
replaced vb2_buffer with vb2_v4l2_buffer in all v4l2 drivers. The
restructuring skipped the v4l2-pci-skeleton, probably because it resides
outside the drivers directory.
The v4l2_buf_ops assume that the passed buffer is a vb2_v4l2_buffer.
This is not the case if the skel_buffer is based on vb2_buffer instead
of vb2_v4l2_buffer.
Replace vb2_buffer with vb2_v4l2_buffer in the skeleton to make sure
that future drivers that are based on the skeleton use vb2_v4l2_buffer.

media: uvcvideo: Refactor teardown of uvc on USB disconnect
Currently, disconnecting a USB webcam while it is in use prints out a
number of warnings, such as:
WARNING: CPU: 2 PID: 3118 at /build/linux-ezBi1T/linux-4.8.0/fs/sysfs/group.c:237 sysfs_remove_group+0x8b/0x90
sysfs group
ffffffffa7cd0780 not found for kobject 'event13'
This has been noticed before. [0]
This is because of the order in which things are torn down.
If there are no streams active during a USB disconnect:
- uvc_disconnect() is invoked via device_del() through the bus
notifier mechanism.
- this calls uvc_unregister_video().
- uvc_unregister_video() unregisters the video device for each
stream,
- because there are no streams open, it calls uvc_delete()
- uvc_delete() calls uvc_status_cleanup(), which cleans up the status
input device.
- uvc_delete() calls media_device_unregister(), which cleans up the
media device
- uvc_delete(), uvc_unregister_video() and uvc_disconnect() all
return, and we end up back in device_del().
- device_del() then cleans up the sysfs folder for the camera with
dpm_sysfs_remove(). Because uvc_status_cleanup() and
media_device_unregister() have already been called, this all works
nicely.
If, on the other hand, there *are* streams active during a USB disconnect:
- uvc_disconnect() is invoked
- this calls uvc_unregister_video()
- uvc_unregister_video() unregisters the video device for each
stream,
- uvc_unregister_video() and uvc_disconnect() return, and we end up
back in device_del().
- device_del() then cleans up the sysfs folder for the camera with
dpm_sysfs_remove(). Because the status input device and the media
device are children of the USB device, this also deletes their
sysfs folders.
- Sometime later, the final stream is closed, invoking uvc_release().
- uvc_release() calls uvc_delete()
- uvc_delete() calls uvc_status_cleanup(), which cleans up the status
input device. Because the sysfs directory has already been removed,
this causes a WARNing.
- uvc_delete() calls media_device_unregister(), which cleans up the
media device. Because the sysfs directory has already been removed,
this causes another WARNing.
To fix this, we need to make sure the devices are always unregistered
before the end of uvc_disconnect(). To this, move the unregistration
into the disconnect path:
- split uvc_status_cleanup() into two parts, one on disconnect that
unregisters and one on delete that frees.
- move v4l2_device_unregister() and media_device_unregister() into
the disconnect path.

media: dvb-usb-v2: Fix incorrect use of transfer_flags URB_FREE_BUFFER
commit
1a0c10ed7bb1 ("media: dvb-usb-v2: stop using coherent memory for
URBs") incorrectly adds URB_FREE_BUFFER after every urb transfer.
It cannot use this flag because it reconfigures the URBs accordingly
to suit connected devices. In doing a call to usb_free_urb is made and
invertedly frees the buffers.
The stream buffer should remain constant while driver is up.

media: venus: fix reported size of 0-length buffers
The last buffer is often signaled by an empty buffer with the
V4L2_BUF_FLAG_LAST flag set. Such buffers were returned with the
bytesused field set to the full size of the OPB, which leads
user-space to believe that the buffer actually contains useful data. Fix
this by passing the number of bytes reported used by the firmware.
