We have more than one C file using this information...

Exactly. hdspmixer needs this information, too. If we move it to the C
file, we would need to duplicate the information in hdspmixer. And then
we forget about it next time hdspm.h needs to be updated.

Ok, I've sent a follow-up patch to avoid to send the whole 180k patch
for the 4th time.

I'll now duplicate this information and send a patch against hdspmixer.
I feel that there should be a better solution like getting the channel
mapping from the driver (sysfs, proc, ioctl or whatever), but that's for
some other time.
