This adds LED triggers for USB host and device. First two patches refactor UDC drivers as requested by Felipe Balbi, the next renames a file and the last is the actual implementation of the LED triggers.
Changes from v5: - Refactoring of USB gadget completion split into two patches (Filipe Balbi) - Removed check for non-NULL req->completion (Filipe Balbi) Changes from v4: - Added performance numbers to the commit message of the last patch (greg k-h). - Replaced BUG_ON with pr_err (Alan Stern, greg k-h). - Used proper coding style for switch statement (greg k-h). - Added comment about NULL argument (greg k-h). - EXPORT_SYMBOL changed to EXPORT_SYMBOL_GPL (greg k-h). - Both triggers are now registerd even if host or gagdet subsystem is not enabled (Bryan Wu, greg k-h). Changes from v3: - usb_gadget_giveback_request() moved outside of CONFIG_HAS_DMA conditioned block. - Added kernel-doc for usb_gadget_giveback_request() (Felipe Balbi). - Removed outdated comment (Alan Stern). - req->complete == NULL is now a bug. Previously, this was ignored (Alan Stern). - File rename moved to a separate commit (greg k-h). Changes from v2: - Host/gadget triggers merged to a single file in usb/common/ (Felipe Balbi). - UDC drivers refactored so that LED trigger works for all of them. Changes from v1: - Moved from drivers/leds/ to drivers/usb/. - Improved Kconfig help. - Linked with other modules rather than being standalone modules.
