This adds LED triggers for USB host and device. First patch refactors
UDC drivers as requested by Felipe Balbi, second is a preparation for
the third, which adds the LED triggers.
Changes from v4:
- 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).
- Added performance numbers to the commit message of the last patch
(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- Removed outdated comment (Alan Stern).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.
