usb: gadget: Add description for module parameter

2021-08-26T11:30:00Z

The description for "qlen" is missing, and there is a description for this parameter in "Documentation/usb/gadget_printer.rst" Signed-off-by: Wei Ming Chen Link: https://lore.kernel.org/r/20210821142647.2904-1-jj251510319013@gmail.com Signed-off-by: Greg Kroah-Hartman

usb: gadget: legacy: printer: Remove unused variable 'driver_desc'

USB: gadget: legacy: Remove redundant license text

2017-11-07T14:45:02Z

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: gadget: printer: Remove pnp_string static buffer

2017-01-24T09:04:08Z

pnp string is usually much shorter than 1k so let's stop wasting 1k of memory for its buffer and make it dynamically alocated. This also removes 1k len limitation for pnp_string and adds a new line after string content if required. Signed-off-by: Krzysztof Opasiak Signed-off-by: Felipe Balbi

usb: gadget: composite: remove redundant bcdUSB setting in legacy

2015-12-15T15:12:41Z

Since composite now overwrites bcdUSB for any gadget, remove setting it in legacy gadgets. All legacy gadgets set 0x0200, the same as the value additionally set by composite, so there is no behaviour change.

usb: gadget: remove gadget_chips.h

2015-08-06T14:35:20Z

This header file contains helpers for quirks based on UDC controller name. Since we have generic quirk bitfields in usb_gadget structure for all of these quirks we don't need to have this header any longer. This patch removes gadget_chips.h file and makes sure that it's no longer included anywhere in kernel sources. Signed-off-by: Robert Baldyga Signed-off-by: Felipe Balbi

usb: gadget: printer: allocate and init otg descriptor by otg capabilities

2015-07-29T14:59:22Z

Allocate and initialize usb otg descriptor according to gadget otg capabilities, add it for each usb configurations. If otg capability is not defined, keep its original otg descriptor unchanged. Reviewed-by: Roger Quadros Signed-off-by: Li Jun Signed-off-by: Felipe Balbi

usb: gadget: remove incorrect init/exit annotations

2015-04-27T19:45:35Z

A recent change introduced a link error for the composite printer gadget driver: `printer_unbind' referenced in section `.ref.data' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o Evidently the unbind function should not be marked __exit here, because it is called through a callback pointer that is not necessarily discarded, __composite_unbind() is indeed called from the error path of composite_bind(), which can never work for a built-in driver. Looking at the surrounding code, I found the same problem in all other composite gadget drivers in both the bind and unbind functions, as well as the udc platform driver 'remove' functions. Those will break if anyone uses the 'unbind' sysfs attribute to detach a device from a built-in driver. This patch removes the incorrect annotations from all the gadget drivers.
