From cfa769695d2bc50b729db6a5973398b24d126c79 Mon Sep 17 00:00:00 2001 From: Andrej Krutak Date: Sun, 18 Sep 2016 20:59:31 +0200 Subject: [PATCH] ALSA: line6: Cleanup podhd initialization Only initialize PCM for POD HD devices that support it. No POD HD seems to support MIDI, thus drop the initialization.
