[alsa-devel] [PATCH v2] ASoC: hdmi-codec: fix non static symbol warnings

[Takashi Sakamoto]

Fixes the following sparse warnings:

$ make C=2 sound/soc/codecs/hdmi-codec.o
sound/soc/codecs/hdmi-codec.c:34:1: warning:
 symbol 'hdmi_device_list' was not declared. Should it be static?
sound/soc/codecs/hdmi-codec.c:80:33: warning:
 symbol 'hdmi_codec_stereo_chmaps' was not declared. Should it be static?
sound/soc/codecs/hdmi-codec.c:87:33: warning:
 symbol 'hdmi_codec_8ch_chmaps' was not declared. Should it be static?
sound/soc/codecs/hdmi-codec.c:354:6: warning:
 symbol 'hdmi_codec_eld_chmap' was not declared. Should it be static?
