If anyone has any objections, please let me know. ------------------ From: Mengdong Lin 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.
