Now that the SPDX tag is in all most driver 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.

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/staging/most files 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.

Check for snd_pcm_ops structures that are only passed as the third
argument to the function snd_pcm_set_ops. As this argument is
constant, so snd_pcm_ops structures having this property can also be
made constant.

Function most_submit_mbo() causes an exception only if either the pointer
mbo or mbo->context equals NULL. From the underlying architecture's point
of view both cases must _not_ come true and would happen only, if something
has tampered with the pointers. This would render runtime code unable to
recover anyway. So, instead trying to hide that things are already
critically out of control we're better off with a WARN_ON() assertion.
This patch replaces the return type of the function most_submit_mbo() with
'void' and adds a WARN_ONCE() assertion. Additionally, code calling the
function is adapted accordingly.

In this file, function names are otherwise used as pointers without &.
A simplified version of the Coccinelle semantic patch that makes this

f(...) { ... }
@@
identifier r.f;

- &f

This patch keeps the process from sleeping after the PCM middle layer has

This patch ensures a fair distribution of buffers, when two AIMs share a
single channel. The AIMs then won't be able to use more than half of all
pre-allocated buffers of the linked channel. However, in case the channel
is not shared, the AIM can exclusively use all available buffers.

This patch adds the aim-sound module of the MOST driver to the kernel's
driver staging area. This module is part of the MOST driver and handles
user space interaction by means of ALSA devices.
This patch is needed in order to have access to MOST synchronous data
through ALSA devices.
