2020-07-09usbip: Use fallthrough pseudo-keywordGustavo A. R. Silva1-2/+2
Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

2017-11-07USB: usbip: Remove redundant license textGreg Kroah-Hartman1-13/+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.

2017-11-01usb: usbip: Convert timers to use timer_setup()Kees Cook1-3/+3
In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.

2016-12-05usbip: vudc: fix: Clear already_seen flag also for ep0Krzysztof Opasiak1-0/+2
ep_list inside gadget structure doesn't contain ep0. It is stored separately in ep0 field. This causes an urb hang if gadget driver decides to delay setup handling. On host side this is visible as timeout error when setting configuration. This bug can be reproduced using for example any gadget with mass storage function.

2016-04-27usbip: vudc: Add vudc_transferIgor Kotrasinski1-0/+506
This file contains a function that simulates USB traffic, based on the one in dummy_hcd. Is also handles udc-directed control requests, and contains functions for setting up and controlling a timer for the emulation.
