From 8b2c7a5c404d7accb9790e1d5a1a518dd0a77a5e Mon Sep 17 00:00:00 2001 From: Wang Xingchao Date: Mon, 24 Jun 2013 23:41:23 -0400 Subject: [PATCH] ALSA: hda - Add In-driver connection info Pin's connection list may change dynamically with hot-plug event on Intel Haswell chip. Users would see connections be "0" in codec#. when play audio on this pin, software driver choose converter from cache connections. So add "In-driver connection" info to avoid confuse when raw connections are different with cache connection.
