From 1884e298c1790a24991c518a8cb8f18ab41f4376 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Daniel=20Gl=C3=B6ckner?= Date: Sat, 9 Jun 2012 21:43:58 -0300 Subject: [PATCH] [media] tvaudio: don't report mono when stereo is received MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The V4L2 spec says reporting mono and stereo at the same time means the hardware can not distinguish between the two. So when we can, we should report only one of them.
