From 9d2b48f7304aafaefbf0794a556ab4e307929d24 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 24 Aug 2015 10:45:27 +0200 Subject: [PATCH] ALSA: hda - Check all inputs for is_active_nid_for_any() The is_active_nid_for_any() function in the generic parser is supposed to check all connections from/to the given widget, but the current code checks only the first input connection (index = 0). This patch corrects the code to check all inputs by passing -1 to index argument.
