USB: usb-skeleton: Remove redundant license text

2017-11-04T10:55:39Z

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: delete non-required instances of include

2014-01-08T23:01:39Z

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. Signed-off-by: Paul Gortmaker Signed-off-by: Greg Kroah-Hartman

USB: usb-skeleton.c: add retry for nonblocking read

2013-07-25T19:01:13Z

Updated skel_read() in usb-skeleton.c. When there is no data in the buffer, we would allow retry for both blocking and nonblocking cases. Original logic give retry only for blocking case. Actually we can also allow retry for nonblocking case. This will reuse the existing retry logic and handle the return of -EAGAIN in one place. Also if the data to be read is short and can be retrieved in quick time, we can also give a chance for nonblocking case and may catch the data and copy it back to userspace in one read() call too.

USB: usb-skeleton.c: fix blocked forever in skel_read

2013-03-25T20:32:20Z

In skel_read,the reader blocked in wait_for_completion before submit bulk in urb. Using processed_urb is for retaining the completion in the case that previous interruptible wait in skel_read was interrupted and complete before next skel_read. Replacing completion with waitqueue can avoid working around the counting nature of completions and fix the bug. Signed-off-by: Du Xing duxing2007@gmail.com Signed-off-by: Greg Kroah-Hartman

USB: usb-skeleton.c: fix compilation error and restored kref_put on fail in skel_open

2012-10-24T21:40:50Z

Fixing compilaton error. Incrementing usage counter only on successful execution of skel_open. Removing redundant locking Some last changes in function skel_open and finally commit 52a7499 Revert "USB: usb-skeleton.c: fix open/disconnect race" introduced a bug in function skel_open, which this patch fixes. Changes since v2: - refactoring - Removing redundant mutex synchronization. Changes since v1: - Fixed accordingly feedback of Oliver Neukum oneukum@suse.de: also need to drop the lock.

USB: usb-skeleton.c: remove err() usage

2012-04-27T18:24:45Z

err() was a very old USB-specific macro that I thought had gone away. This patch removes it from being used in the driver and uses dev_err() instead. Signed-off-by: Greg Kroah-Hartman
