e6d0db1d47 [media] cx25840: fix regression in analog support hue/saturation controls
Fix regression in HVR-1800 analog support hue/saturation controls.

The changes made for the cx23888 caused regressions in the analog
support for cx23885/cx23887 based boards (partly due to changes in the
locations of the hue/saturation controls).  As a result the wrong
registers were being overwritten.

Add code to use the correct registers if it's a cx23888

Validated with the following boards:

HVR-1800 retail (0070:7801)
HVR-1800 OEM (0070:7809)
HVR-1850 retail (0070:8541)

Thanks to Steven Toth and Hauppauge for	loaning	me various boards to
regression test	 with.

ba50e7e16b [media] cx25840: fix regression in HVR-1800 analog support
The refactoring of the cx25840 driver to support the cx23888 caused breakage
with the existing support for cx23885/cx23887 analog support.  Rework the
routines such that the new code is only used for the 888.

Validated with the following boards:

HVR-1800 retail (0070:7801)
HVR-1800 OEM (0070:7809)
HVR_1850 retail (0070:8541)

a7deca6fa7 [media] cx231xx: don't DMA to random addresses
Commit 7a6f6c29d2 (cx231xx: use
URB_NO_TRANSFER_DMA_MAP) was intended to avoid mapping the DMA buffer
for URB twice. This works for the URBs allocated with usb_alloc_urb(),
as those are allocated from cohernent DMA pools, but the flag was also
added for the VBI and audio URBs, which have a manually allocated area.
This leaves the random trash in the structure after allocation as the
DMA address, corrupting memory and preventing VBI and audio from
working. Letting the USB core map the buffers solves the problem.

Fix this, as well as potential memory leaks due to not calling
v4l2_fh_release() on some error paths.

Also remove some error logs printed for events that aren't critical and
are normal conditions for some system configurations.

Also check if the device have been properly run-time enabled during
video node open.

d0da3c3565 [media] s5p-fimc: Don't create multiple active links to same sink entity
The driver is supposed to create active media link from sensor N
(or its corresponding s5p-mipi-csis entity) to FIMC.N by default.
Instead s5p-mipi-csis.N entity gets  always connected by a default
active link to FIMC.N, regardless of there are parallel bus sensor
entities already connected to FIMC.N. Correct this.

de87897af0 [media] bw-qcam: driver and pixfmt documentation fixes
Fix the documentation of the Y4 and Y6 formats.
Fix a poll() issue, add support for enum_frmsizes, set the proper
parent device and fix a few compliance issues.

Tested with an actual Connectix B&W parallel port webcam, both on a
little-endian and a big-endian platform. This driver has never been
so good, doing 320x240 at 1 frame per second :-)

I know, nobody cares, but still it is cool that linux can still support
this old webcam.

c44ff8fa02 [media] tuner-core: return the frequency range of the correct tuner
The frequency range of the current tuner (radio or TV) was returned
instead of the frequency range of the requested tuner (which depends
on the device node).

This bug caused the frequency range of the radio tuner to be returned
when G_TUNER was called on a video node.

a5ee6e41b2 [media] v4l2-dev.c: fix g_parm regression in determine_valid_ioctls()
The field current_norm does not have to be set for g_parm to be a valid
ioctl. Remove that check, but add a check whether this is a video node
instead as g_parm only makes sense for those nodes.

Even if the best results are indeed achieved with both AGC and AWB
enabled, the webcam is capable of setting these independently, and the
user can see the difference of any of the 4 combinations of these two
boolean controls.

Removing the dependency from one another simplifies the code and gives
more control to the user.
