docs-rst: kernel-doc: fix typedef output in RST format
When using a typedef function like this one:
typedef bool v4l2_check_dv_timings_fnc (const struct v4l2_dv_timings * t, void * handle);
The Sphinx C domain expects it to create a c:type: reference,
as that's the way it creates the type references when parsing
a c:function:: declaration.
So, a declaration like:
.. c:function:: bool v4l2_valid_dv_timings (const struct v4l2_dv_timings * t, const struct v4l2_dv_timings_cap * cap, v4l2_check_dv_timings_fnc fnc, void * fnc_handle)
Will create a cross reference for :c:type:`v4l2_check_dv_timings_fnc`.
So, when outputting such typedefs in RST format, we need to handle
this special case, as otherwise it will produce those warnings:
./include/media/v4l2-dv-timings.h:43: WARNING: c:type reference target not found: v4l2_check_dv_timings_fnc
./include/media/v4l2-dv-timings.h:60: WARNING: c:type reference target not found: v4l2_check_dv_timings_fnc
./include/media/v4l2-dv-timings.h:81: WARNING: c:type reference target not found: v4l2_check_dv_timings_fnc
So, change the kernel-doc script to produce a RST output for the
above typedef as:
.. c:type:: v4l2_check_dv_timings_fnc

``bool v4l2_check_dv_timings_fnc (const struct v4l2_dv_timings * t, void * handle);``

From the old description people still can't get what's the exact
difference between nr_cpus and maxcpus. Especially in kdump kernel
nr_cpus is always suggested if it's implemented in the ARCH. The
reason is nr_cpus is used to limit the max number of possible cpu
in system, the sum of already plugged cpus and hot plug cpus can't
exceed its value. However maxcpus is used to limit how many cpus
are allowed to be brought up during bootup.

Right now, for a struct, kernel-doc produces the following output:

**Definition**
::
struct v4l2_prio_state {
atomic_t prios[4];
};
**Members**
``atomic_t prios[4]``
array with elements to store the array priorities
Putting a member name in verbatim and adding a continuation line
causes the LaTeX output to generate something like:
item[atomic_t prios\[4\]] array with elements to store the array priorities
Everything inside "item" is non-breakable, with may produce
lines bigger than the column width.
Also, for function members, like:
int (* rx_read) (struct v4l2_subdev *sd, u8 *buf, size_t count,ssize_t *num);
It puts the name of the member at the end, like:
int (*) (struct v4l2_subdev *sd, u8 *buf, size_t count,ssize_t *num) read
With is very confusing.
The best is to highlight what really matters: the member name.
is a secondary information.
So, change kernel-doc, for it to produce the output on a different way:
**Members**
``prios[4]``
array with elements to store the array priorities
Also, as the type is not part of LaTeX "item[]", LaTeX will split it into
multiple lines, if needed.
So, both LaTeX/PDF and HTML outputs will look good.
It should be noticed, however, that the way Sphinx LaTeX output handles
things like:
Foo
bar
is different than the HTML output. On HTML, it will produce something
like:
**Foo**
bar
While, on LaTeX, it puts both foo and bar at the same line, like:
**Foo** bar

[media] vb2: remove TODO comment for dma-buf in QBUF
There is a TODO comment about the dma-buf being mapped in VIDIOC_QBUF
instead of doing it closer to when the actual DMA is going to happen
when the buffers are queued in the driver (i.e: __enqueue_in_driver).
But there is a reason to do it earlier in QBUF, and is that userspace
has no way to know if a exported dma-buf can be imported successfully
and so relies on QBUF succeeding as indication that the dma-buf mapped.
If QBUF fails, the application can fallback to another streaming I/O
method. But moving the dma-buf mapping later when queueing the buffers
can be too late for userspace to recover, since it may had dropped the
buffer(s) already when it knows that the dma-buf mapping failed.
So remove the TODO instead and change the comment to explain this.
