From ef8e39b51f24c8ac907e1f1995910ee3083375e0 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 10 Feb 2014 11:43:41 +0100 Subject: [PATCH] ALSA: hda - Fix undefined symbol due to builtin/module mixup Even after the fix for leftover kconfig handling (commit f8f1becf), the current code still doesn't handle properly the builtin/module mixup case between the core snd-hda-codec and other codec drivers. For example, when CONFIG_SND_HDA_INTEL=y and CONFIG_SND_HDA_CODEC_HDMI=m, it'll end up with an unresolved symbol snd_hda_parse_hdmi_codec. This patch fixes the issue. Now codec->parser points to the parser object *only* when a module (either generic or HDMI parser) is loaded and bound. When a builtin symbol is used, codec->parser still points to NULL. This is the difference from the previous versions.
