From 991452a21b76e5e1bba2fcf9c024ab69067f5656 Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Sun, 12 Aug 2012 22:27:08 -0300 Subject: [PATCH] [media] rtl28xxu: generalize streaming control Move rtl2831u LED from streaming control to power control. It changes LED behavior slightly but who cares :) After that same streaming control can be used for both rtl2831u and rtl2832u.
