USB: gadget: legacy: Remove redundant license text

Now that the SPDX tag is in all USB files, that identifies the license
in a specific and legally-defined manner. So the extra GPL text wording
can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text. And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.

USB: add SPDX identifiers to all remaining files in drivers/usb/

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Update the drivers/usb/ and include/linux/usb* files with the correct
SPDX license identifier based on the license text in the file itself.
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

usb: gadget: add f_uac1 variant based on a new u_audio api

This patch adds a new function 'f_uac1'
(f_uac1 with virtual "ALSA card") that
uses recently created u_audio API. Comparing
to legacy f_uac1 function implementation it
doesn't require any real Audio codec to be
present on the device. In f_uac1 audio
streams are simply sinked to and sourced
from a virtual ALSA sound card created
using u_audio API.

Legacy f_uac1 approach is to write audio
samples directly to existing ALSA sound
card

f_uac1 approach is more generic/flexible
one - create an ALSA sound card that
represents USB Audio function and allows to
be used by userspace application that
may choose to do whatever it wants with the
data received from the USB Host and choose
to provide whatever it wants as audio data
to the USB Host.

f_uac1 also has capture support (gadget->host)
thanks to easy implementation via u_audio.
By default, capture interface has 48000kHz/2ch
configuration, same as playback channel has.

f_uac1 descriptors naming convention
uses f_uac2 driver naming convention that
makes it more common and meaningful.

Comparing to f_uac1_legacy, the f_uac1 doesn't
have volume/mute functionality. This is because
the f_uac1 volume/mute feature unit was dummy
implementation since that driver creation (2009)
and never had any real volume control or mute
functionality, so there is no any difference
here.

Since f_uac1 functionality, exposed
interface to userspace (virtual ALSA card),
input parameters are so different comparing
to f_uac1_legacy, that there is no any
reason to keep them in the same file/module,
and separate function was created.

g_audio can be built using one of existing
UAC functions (f_uac1, f_uac1_legacy or f_uac2)

In this patch, we introduce a parameter for the number for usb request,

usb: gadget: Convert use of __constant_cpu_to_le16 to cpu_to_le16

In big endian cases, macro cpu_to_le16 unfolds to __swab16 which
provides special case for constants. In little endian cases,
__constant_cpu_to_le16 and cpu_to_le16 expand directly to the
same expression. So, replace __constant_cpu_to_le16 with
cpu_to_le16 with the goal of getting rid of the definition of
__constant_cpu_to_le16 completely.

The semantic patch that performs this transformation is as follows:

@@expression x;@@

- __constant_cpu_to_le16(x)
+ cpu_to_le16(x)

usb: gadget: remove incorrect __init/__exit annotations

usb: gadget: remove incorrect __init/__exit annotations

A recent change introduced a link error for the composite
printer gadget driver:

`printer_unbind' referenced in section `.ref.data' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o

Evidently the unbind function should not be marked __exit here,
because it is called through a callback pointer that is not necessarily
discarded, __composite_unbind() is indeed called from the error path of
composite_bind(), which can never work for a built-in driver.

Looking at the surrounding code, I found the same problem in all other
composite gadget drivers in both the bind and unbind functions, as
well as the udc platform driver 'remove' functions. Those will break
if anyone uses the 'unbind' sysfs attribute to detach a device from a
built-in driver.

This patch removes the incorrect annotations from all the gadget
drivers.

usb: gadget: f_uac1: convert to new function interface with backward compatibility

Converting uac1 to the new function interface requires converting
the USB uac1's function code and its users.

This patch converts the f_uac1.c to the new function interface.

The file is now compiled into a separate usb_f_uac1.ko module.

The old function interface is provided by means of a preprocessor
conditional directives. After all users are converted, the old interface
can be removed.

usb: gadget: f_uac1: prepare for separate compilation

Integrating configfs requires converting f_uac1 to new function interface,
which in turn requires converting it to the new function interface,
which involves separate compilation of f_uac1.c into usb_f_uac1.ko.
u_uac1.c contains some module parameters. After this patch is applied
they are still a part of the resulting g_audio.ko, but can be guarded
with a compatiblity flag which will be removed when no users of the old
function interface of f_uac1 are left.
