usb: gadget: remove max support speed info in bind operation

2023-08-22T12:48:33+00:00

Take ecm_bind() for example, it call gadget_is_{*}speed() API to show gadget max support speed, it is not much help, remove the API usage here is safe. Similar change apply to acm,eem,loopback,ncm,obex,rndis,serial, sourcesink,subset functions.

usb: gadget: f_serial: Ensure gserial disconnected during unbind

2022-01-26T12:57:59+00:00

Some UDCs may return an error during pullup disable as part of the unbind path for a USB configuration. This will lead to a scenario where the disable() callback is skipped, whereas the unbind() still occurs. If this happens, the u_serial driver will continue to fail subsequent binds, due to an already existing entry in the ports array. Ensure that gserial_disconnect() is called during the f_serial unbind, so the ports entry is properly cleared.

This avoids a null pointer dereference in f_{ecm,eem,hid,loopback,printer,rndis,serial,sourcesink,subset,tcm} by simply reusing the 5gbps config for 10gbps.

USB: gadget: function: Remove redundant license text

2017-11-07T14:45:02+00:00

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/

2017-11-04T10:48:02+00:00

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.
