USB: move many drivers to use DEVICE_ATTR_RW

2018-01-24T07:49:51Z

Instead of "open coding" a DEVICE_ATTR() define, use the DEVICE_ATTR_RW() macro instead, which does everything properly instead. This does require a few static functions to be renamed to work properly, but thanks to a script from Joe Perches, this was easily done.

USB: chipidea: Remove redundant license text

2017-11-07T14:45:01Z

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/

2017-11-04T10:48:02Z

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: chipidea: properly handle host or gadget initialization failure

2017-05-18T00:55:22Z

If ci_hdrc_host_init() or ci_hdrc_gadget_init() returns error and the error != -ENXIO, as Peter pointed out, "it stands for initialization for host or gadget has failed", so we'd better return failure rather continue. And before destroying the otg, i.e ci_hdrc_otg_destroy(ci), we should also check ci->roles[CI_ROLE_GADGET]. Signed-off-by: Jisheng Zhang Signed-off-by: Peter Chen
