Hi Gustavo,
Thanks a lot for the patch.

Make use of the struct_size() helper instead of an open-coded
version
in order to avoid any potential type mistakes, in particular in
the
context in which this code is being used.
So, replace code of the following form:
sizeof(*resp) + props_count * sizeof(struct
gb_power_supply_props_desc)
with:
struct_size(resp, props, props_count)
This code was detected with the help of Coccinelle.

What are the odds of 2 people changing same code in greybus in
the same day :).
But it happened, so as Johan asked please rebase on top of his
patch. that would be great.
