From b907900ec4065e1d9b65fafa05fd6601b6a2ffc7 Mon Sep 17 00:00:00 2001 From: Andrej Krutak Date: Wed, 5 Oct 2016 17:46:09 +0200 Subject: ALSA: line6: Fix POD X3 Live audio input The commit c039aaa77a7d1d9375665a8b59ec16dc7d23e259 was incomplete, missing part of the setup for Live. This makes also audio input work, in addition to audio output.

In this situation, it is safe to control the micmute led according to user's choice of muting/unmuting the current input device, since only current input device path is active, while other input device paths are inactive and powered down.

In former commit, a function call of compatibility layer for ALSA sequencer core was obsoleted by an alternative. Although, the alternative gets a pointer to kernel stack due to mis-programming. As a result, ALSA sequencer core unexpectedly refers over kernel stack.
