[PATCH 0/4] Staging: octeon-usb: Fixes and Coding style applied.

[Georgios Tsotsos]

Hello, 

Previously patches were sent with wrong cover format, please ignore.

I am sending four patches which trying to resolve TODO list requirements 
no 45 about octeon-usb. 
There are SPDX licence additions on c and header files. 
Checkpatch warnings are resolved,also a notice about CVMX_WAIT_FOR_FIELD32 macro.
It could improve readability and maintenance of this module if function
cvmx_usb_poll_channel() break down (and probably some others too)

Georgios Tsotsos (4):
  Staging: octeon-usb: Adds SPDX License Identifier
  Staging: octeon-usb: Applying coding style for column width.
  Staging: octeon-usb: Change coding style for CVMX_WAIT_FOR_FIELD32 marco.
  Staging: octeon-usb: Adds SPDX License Identifier for header file

[PATCH 2/4] Staging: octeon-usb: Applying coding style for column width.

[Georgios Tsotsos]

This patch resolves the warnings as its refereed to TODO list.
There are also a code style issues that could be resolved via breaking
down cvmx_usb_poll_channel().
