[PATCH -next] ASoC: hdmi-codec: fix non static symbol warnings

[Wei Yongjun]

From: Wei Yongjun <weiyongjun1@huawei.com>

Fixes the following sparse warnings:

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?

Unfortunately, this patch causes conflict to Mark's PR[0], due to a 
commit 8480ac567959 ("ASoC: hdmi-codec: remove HDMI device 
unregister")[1]. I think it better for you to post again with rebasing 
this on the PR, however it depends on Mark's maintenance policy (he 
could resolve the conflict by his hand and apply).

I don't seem to have this patch?

If it's in what went to Linus already I'd prefer a rebase as I'd have to
dig out an old tree, I will make some effort to do merges if I can find
a baseline to apply patches against though sometimes if things are
complicated enough I'll ask people to do that for me.
