From e4973e1e5a42072ce88736ba0e39e4b8fc6c3c44 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 18 Nov 2008 09:32:42 +0100 Subject: [PATCH] ALSA: hda - Create jack detection elements in build_controls The jack detection input elements should be created in build_controls callback instead of init callback because init can be called multiple times by suspend/resume and power-saving.
