2017-11-07USB: gadget: udc: Remove redundant license textGreg Kroah-Hartman1-6/+0
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.

2017-11-04USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman1-0/+1
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.

2015-02-11xilinx usb2 gadget: get rid of incredibly annoying compile warningLinus Torvalds1-2/+2
This one was driving me mad, with several lines of warnings during the allmodconfig build for a single bogus pointer cast. The warning was so verbose due to the indirect macro expansion explanation, and the whole thing was just for a debug printout. The bogus pointer-to-integer cast was pointless anyway, so just remove it, and use '%p' to show the pointer. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2014-11-03usb: gadget: remove unnecessary 'driver' argumentFelipe Balbi1-2/+1
now that no UDC driver relies on the extra 'driver' argument to ->udc_stop(), we can safely remove it. This commit is based on previous work by Robert Baldyga <r.baldyga@samsung.com> which can be found at [1]; however that patch turned out to have a high probability of regressing many UDC drivers because of a blind search & replace s/driver/$udc->driver/ which caused the 'driver' argument to stop_activity() to be a valid non-NULL pointer when it should be NULL, thus causing UDCs to mistakenly call gadget driver's ->disconnect() callback.
