Comment 1 for bug 1085412

I tested the hwpack config, and did some other tests.
It is not really an error in l-i-t per se, it is how the yaml library parses the string or how it is interpreting the value.

If we quote the mmc_id value like:
mmc_id: '1:1'

it will pick it up as a valid string, otherwise it picks it up (I guess) as a number, which yelds 61 as a result value.
Need to check how the other hwpack config files are using the mmc_id value.
