Pull documentation updates from Jonathan Corbet:
"This was a reasonably active cycle for documentation; this includes:
- Some kernel-doc cleanups. That script is still regex onslaught from
hell, but it has gotten a little better.
- Improvements to the checkpatch docs, which are also used by the
tool itself.
- A major update to the pathname lookup documentation.
- Elimination of :doc: markup, since our automarkup magic can create
references from filenames without all the extra noise.
- The flurry of Chinese translation activity continues.
Plus, of course, the usual collection of updates, typo fixes, and
warning fixes"

A type of inconsistency that can show up in control URBs is when the
setup packet's wLength value does not match the URB's
transfer_buffer_length field. The two should always be equal;
differences could lead to information leaks or undefined behavior for
OUT transfers or overruns for IN transfers.
This patch adds a test for such mismatches during URB submission. If
the test fails, the submission is rejected with a -EBADR error code
(which is not used elsewhere in the USB core), and a debugging message
is logged for people interested in tracking down these errors.

Keep the textual reference to ch9.h as it was prior to commit
caa93d9bd2 ("usb: Fix up movement of USB core kerneldoc location").
As linux/usb/ch9.h does not contain comments anymore, explain
that drivers/usb/common/common.c includes such header and provides
declarations of a few utilities routines for manipulating the data types
from ch9.h. Also mention that drivers/usb/common/debug.c contains
some functions for creating debug output.

Commit 855b35ea96c4 ("usb: common: move function's kerneldoc next to its
definition") moved the USB common function documentation out of the
linux/usb/ch9.h header file into drivers/usb/common/common.c and
drivers/usb/common/debug.c, which causes the following 'make htmldocs'
build warning:
include/linux/usb/ch9.h:1: warning: no structured comments found
Fix that up by pointing the documentation at the correct location.

The typec_bus.rst asks for documentation of those two
functions, but they don't exist:
./drivers/usb/typec/bus.c:1: warning: 'typec_altmode_unregister_driver' not found
./drivers/usb/typec/bus.c:1: warning: 'typec_altmode_register_driver' not found
Also, they're not declared on bus.c but, instead, at a header
file (typec_altmode.h).
So, add documentation for both functions at the header and
change the kernel-doc markup under typec_bus.rst to point
to the right place.
While here, also place the documentation for both structs
declared on typec_altmode.h at the rst file.

The :c:type:`foo` only works properly with structs before
Sphinx 3.x.
On Sphinx 3.x, structs should now be declared using the
.. c:struct, and referenced via :c:struct tag.
As we now have the automarkup.py macro, that automatically
convert:
struct foo
into cross-references, let's get rid of that, solving
several warnings when building docs with Sphinx 3.x.
