Exporting the ELD bytes to userspace allows an application to select

This looks good, but I was unable to test it. Obviously amixer or
alsamixer is unable to show anything about an ELD mixer element,
You can use amixer cget command to retrieve the information.
but
shouldn't there be something about it shown under /proc/asound/card0/,
or am I mistaken.
It's specific to driver. HD-audio has one, but it doesn't show the
whole ELD but only parsed contents.
Thanks,
I managed the read the ELD bytes with:
amixer -c0 cget iface=PCM,name='ELD',device=0
And the numbers change a bit when I connect to a different TV, so:
