[LEDE-DEV] [PATCH 1/2] kernel: add package for usbport LED trigger

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

This is upstream alternative for LEDE's ledtrig-usbdev. It's main
advantages are:
1) Support for assigning more than 1 USB port to the LED
2) Setting proper state when activating with device already connected
3) FWIW it's an upstream driver

+  This driver allows LEDs to be controlled by USB events. Enabling this
+  trigger allows specifying list of USB ports that should turn on LED
+  when some USB device gets connected.
+  If possible it should be prefered over similar ledtrig-usbdev.
