Thanks for the patch! Acked-by: Liviu Dudau <liviu.dudau@xxxxxxx>

This is starting to get embarrassing :) I'm not sure why I didn't see the warnings when
I did my builds, but I would like to make changes so that in the future I can catch
situations like this. Do you change the flags of the default make multi_v7_defconfig?

I will apply the patch to the HLDCD tree and send Dave an updated pull request.

Best regards,
Liviu
