From c55a97d7538d5f3abbee5486e37e56e896478fbd Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Tue, 22 Apr 2008 14:45:41 -0300 Subject: V4L/DVB (7312): pvrusb2: Indicate streaming status via LED Most of this originates from Michael Krufky ; these changes move LED control into separate functions. This is the first step in new work to make LED control a device-specific attribute.
