2f90857781 media: qcom: camss: Fix overflows in clock rate calculations
Because of u32 type being used to store pixel clock rate, expression used
to calculate pipeline clocks (pixel_clock * bpp) produces wrong value due
to integer overflow. This patch changes data type used to store, pass and
retrieve pixel_clock from u32 to u64 to make this mistake less likely to
be repeated in the future.

78c2cc28df media: camss: use v4l2_get_link_freq() to calculate the relevant clocks
There are places in the camss driver where camss_get_pixel_clock() is
called to get the pixel rate (using V4L2_CID_PIXEL_RATE control) and to
calculate the link frequency from it. There is a case when this would
not work: when V4L2_CID_PIXEL_RATE gets the rate at which the pixels are
read (sampled) from the sensor's pixel array, and this rate is different
from the pixel transmission rate over the CSI link, the link frequency
value can't be calculated from the pixel rate. One needs to use
V4L2_CID_LINK_FREQ to get the link frequency in this case.

Replace such calls to camss_get_pixel_clock() with calls to a wrapper
around v4l2_get_link_freq(). v4l2_get_link_freq() tries V4L2_CID_LINK_FREQ
first, and if it is not implemented by the camera sensor driver, falls
back to V4L2_CID_PIXEL_RATE to calculate the link frequency value from.

Calls to camss_get_pixel_clock() from vfe_[check,set]_clock_rates()
are left intact as it looks like this VFE clock does depend on the
rate the pixel samples comes out of the camera sensor, not on the
frequency at which the link between the sensor and the CSI receiver
operates.

6a49401e15 media: usbtv: constify static structs
Constify two static structs which are never modified to allow the
compiler to put them in read-only memory.

The only usage of norm_params is only read from it in
usbtv_configure_for_norm(). Making it const shrinks the resulting
ko-file with 300 bytes (tested with gcc 10).

The only usage of usbtv_ioctl_ops is to put its address to the ioctl_ops
field in the video_device struct. Making it const moves ~1kb to
read-only memory.

c49206786e media: dvb-usb: Fix use-after-free access
dvb_usb_device_init() copies the properties to the own data, so that
the callers can release the original properties later (as done in the
commit 299c7007e9 ("media: dw2102: Fix memleak on sequence of
probes")).  However, it also stores dev->desc pointer that is a
reference to the original properties data.  Since dev->desc is
referred later, it may result in use-after-free, in the worst case,
leading to a kernel Oops as reported.

This patch addresses the problem by allocating and copying the
properties at first, then get the desc from the copied properties.

13a79f14ab media: dvb-usb: Fix memory leak at error in dvb_usb_device_init()
dvb_usb_device_init() allocates a dvb_usb_device object, but it
doesn't release the object by itself even at errors.  The object is
released in the callee side (dvb_usb_init()) in some error cases via
dvb_usb_exit() call, but it also missed the object free in other error
paths.  And, the caller (it's only dvb_usb_device_init()) doesn't seem
caring the resource management as well, hence those memories are
leaked.

This patch assures releasing the memory at the error path in
dvb_usb_device_init().  Now dvb_usb_init() frees the resources it
allocated but leaves the passed dvb_usb_device object intact.  In
turn, the dvb_usb_device object is released in dvb_usb_device_init()
instead.
We could use dvb_usb_exit() function for releasing everything in the
callee (as it was used for some error cases in the original code), but
releasing the passed object in the callee is non-intuitive and
error-prone.  So I took this approach (which is more standard in Linus
kernel code) although it ended with a bit more open codes.

Along with the change, the patch makes sure that USB intfdata is reset
and don't return the bogus pointer to the caller of
dvb_usb_device_init() at the error path, too.

e89dbb12b6 media: docs: pixfmt: use section titles for bayer formats
The bayer formats have a subtitle, specifying how many bits
they use. Add a title markup to those, as otherwise they
look weird, specially at the PDF output.

43774190ff media: ext-ctrls-jpeg.rst: cleanup V4L2_CID_JPEG_COMPRESSION_QUALITY text
The text is repeating the name of the control, which causes
it to be displayed outside the page with PDF output.

Besides that, this is the only JPEG control doing that. Removing
the name duplication doesn't affect the description, but, instead,
make it nicer.

235ad7e647 media: ext-ctrls-codec.rst: simplify a few tables
Those tables nicely fits on PDF output without any hack.
Yet, they are using a very small font, and have tabularcolumns.

Clean it up, and convert it to an ASCII artwork, as it
makes easier to see that no hacks are needed to display it ;-)

f23f5c7094 media: ext-ctrls-codec-stateless.rst: change a FWHT flag description
Instead of using "- 1", use "minus one".

The reason is that, if the table is split like:

  V4L2_FWHT_FL_COMPONENTS_NUM_MSK  0x00070000  The number of color components
                                               - 1.

One might not realize the meaning of the second line.

As a side effect, using text instead of arabic numbers is
more appropriate for formal documents like this spec.

571610162b media: docs: sliced-vbi: fix V4L2_SLICED_WSS_625 docs
While fixing issues with PDF generation, I noticed that
bit 8 was missing for WSS 625 format.

While here, convert the literal block into a tables,
as it becomes more visible.

I opted to move the payload into a separate table, as
Sphinx has troubles with complex nested tables.

This way, it should work fine on both html and LaTeX/PDF
formats.

a78801a443 media: control.rst: use a table for V4L2_CID_POWER_LINE
The default way to document control enums is via tables.

Use one here too. As the table is simple, just use ASCII
artwork.

b0b6ef0bb2 media: colorspaces-details.rst: drop tabularcolumns
Those tables have small cells that fit nicely without requiring
line beaks.

So, they don't need tabular columns, as Sphinx/LaTeX
can adjust the width on such tables.
