usb/c67x00: Replace tasklet with work

2021-01-26T17:36:37+00:00

Tasklets have long been deprecated as being too heavy on the system by running in irq context - and this is not a performance critical path. If a higher priority process wants to run, it must wait for the tasklet to finish before doing so. c67x00_do_work() will now run in process context and have further concurrency (tasklets being serialized among themselves), but this is done holding the c67x00->lock, so it should be fine. Furthermore, this patch fixes the usage of the lock in the callback as otherwise it would need to be irq-safe.

USB: c67x00: Use the correct style for SPDX License Identifier

2020-03-17T19:03:28+00:00

This patch corrects the SPDX License Identifier style in header files related to Cypress C67X00 USB Controller. For C header files Documentation/process/license-rules.rst mandates C-like comments (opposed to C source files where C++ style should be used). Changes made by using a script provided by Joe Perches here: https://lkml.org/lkml/2019/2/7/46.

USB: c67x00: 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.

USB: make hcd.h public (drivers dependency)

2010-05-20T20:21:30+00:00

The usbcore headers: hcd.h and hub.h are shared between usbcore, HCDs and a couple of other drivers (e.g. USBIP modules). So, it makes sense to move them into a more public location and to cleanup dependency of those modules on kernel internal headers. This patch moves hcd.h from drivers/usb/core into include/linux/usb/ Signed-of-by: Eric Lescouet Cc: Alan Stern Signed-off-by: Greg Kroah-Hartman
