When the length of the transfer is an exact multiple of IN endpoint MPS
in the ring buffer, transfer one byte less to avoid zero-length packet.
Otherwise the application running on the host may conclude that there
is no more data to be received (i.e. the transaction has completed),
hence not triggering another I/O Request Packet (IRP).

In case the ring buffer is empty, ring_buf_get_claim() returns a zero

Currently the cdc_acm implementation pass the data to usb_transfer() by
a chunk of IN endpoint MPS. This has 2 drawbacks:
- at higher throughput, each transfer needs 2 packets due to the need of
an extra ZLP;
- a temporary buffer of size USB MPS is needed.
This patch improves the memory consumption and performances by passing
the ring buffer directly to usb_transfer(). It only has a small
performance degradation when the ring buffer wraps and less than a IN
endpoint MPS has to be sent.

setting/resetting endpoints is required when switching to alternate
interfaces. This is a common operation for usb audio class.
When audio device is enumerated host invokes set_interface request
to alternate with 0 endpoints associated. That operation lead to
disable never enabled endpoints. With previous solution error message
will appear.
This commit limits error messages to be present only if endpoint
was configured/enabled before and there was a problem when trying
to configure/enable it for the first time.

I think people might be reading differences into 'if' and 'depends on'
that aren't there, like maybe 'if' being needed to "hide" a symbol,
while 'depends on' just adds a dependency.
There are no differences between 'if' and 'depends on'. 'if' is just a
shorthand for 'depends on'. They work the same when it comes to creating
implicit menus too.
The way symbols get "hidden" is through their dependencies not being
satisfied ('if'/'depends on' get copied up as a dependency on the
prompt).
Since 'if' and 'depends on' are the same, an 'if' with just a single
symbol in it can be replaced with a 'depends on'. IMO, it's best to
avoid 'if' there as a style choice too, because it confuses people into
thinking there's deep Kconfig magic going on that requires 'if'.
Going for 'depends on' can also remove some nested 'if's, which
generates nicer symbol information and docs, because nested 'if's really
are so simple/dumb that they just add the dependencies from both 'if's
to all symbols within.
Replace a bunch of single-symbol 'if's with 'depends on' to despam the
Kconfig files a bit and make it clearer how things work. Also do some
other minor related dependency refactoring.
The replacement isn't complete. Will fix up the rest later. Splitting it
a bit to make it more manageable.
(Everything above is true for choices, menus, and comments as well.)
Detected by tweaking the Kconfiglib parsing code. It's impossible to
detect after parsing, because 'if' turns into 'depends on'.

If for example user configures composite device with hid

Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).
Go for the most common style:
- Indent properties with a single tab, including for choices.
Properties on choices work exactly the same syntactically as
properties on symbols, so not sure how the no-indentation thing
happened.
- Indent help texts with a tab followed by two spaces
- Put a space between 'config' and the symbol name, not a tab. This
also helps when grepping for definitions.
- Do '# A comment' instead of '#A comment'

subsys/usb/Kconfig 'source's subsys/usb/class/Kconfig (which in turn
'source's subsys/usb/class/netusb/Kconfig) within an
'if USB_DEVICE_STACK', so the dependencies on USB_DEVICE_STACK added
within those files are redundant.
'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. Dependencies on menus work similarly. There are no
"conditional includes" in Kconfig, so 'if FOO' has no special meaning
around a source. Conditional includes wouldn't be possible, because an
if condition could include (directly or indirectly) forward references
to symbols not defined yet.
Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.
