8f20f2dca8 staging: most: usb: clear functional stall on OUT endpoint
For the MOST packet channel there are two dedicated USB endpoints. But
internally the hardware has actually one channel for data forwarding from
and to MOST. To have the hardware clean up its state machine correctly in
case of an error, both USB pipes need to be reset.  This patch triggers the
host to also clear the OUT endpoint's halt condition in case an IN endpoint
has signaled to be stalled.

c1dcb35bf1 staging: most: Remove redundant license text
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.

1a79f22de8 staging: most: add SPDX identifiers to all most driver files
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.
