Since you will respin, could you please fix the position of the data in
order to stick to the original one? Same thing for the list at the end.
One flag introduced in 2.6.38 is missing, and the flags are now sorted.
See comments below.
If you need to check what should be the final result after the merge of
every hwmods series, you can check here:

The order is slightly different due to a sort that was not done before.
