From 05c3b36e539627b7aed67d038381d0d9fa9d61e7 Mon Sep 17 00:00:00 2001 From: David Henningsson Date: Tue, 31 Jan 2012 09:04:15 +0100 Subject: [PATCH] ALSA: HDA: Fix jack creation for codecs with front and rear Line In If a codec has both a front and a rear Line In, two controls both named "Line Jack" will be created, which causes parsing to fail. While a long term solution might be to name the jacks differently, this extra check is consistent with what is already being done in many auto-parsers, and will also protect against other cases when two inputs have the same label.
