From 2e4010695a44d36c2f5cd5bbe0724d32f31c1590 Mon Sep 17 00:00:00 2001 From: Mengdong Lin Date: Thu, 28 Mar 2013 05:20:22 -0400 Subject: ALSA: hda - bug fix on return value when getting HDMI ELD info commit 2ef5692efad330b67a234e2c49edad38538751e7 upstream. In function snd_hdmi_get_eld(), the variable 'ret' should be initialized to 0. Otherwise it will be returned uninitialized as non-zero after ELD info is got successfully. Thus hdmi_present_sense() will always assume ELD info is invalid by mistake, and /proc file system cannot show the proper ELD info.
