* HID: migrate USB LED driver from usb misc to hidHeiner Kallweit2016-06-171-0/+288
This patch migrates the USB LED driver to the HID subsystem. Supported are Dream Cheeky Webmail Notifier / Friends Alert and Riso Kagaku Webmail Notifier. Benefits: - Avoid using USB low-level calls and use the HID subsystem instead (as this device provides a USB HID interface) - Use standard LED subsystem instead of proprietary sysfs entries, this allows e.g. to use the device with features like triggers Successfully tested with a Dream Cheeky Webmail Notifier and a Riso Kagaku Webmail Notifier compatible device.
