This was not allocating enough bytes. There are two issue here. First, there was a typo where it was taking the size of the pointer instead of the size of the struct, "sizeof(qp->intf_clks)" vs "sizeof(*qp->intf_clks)". Second, it's an array of "cd_num" clocks so we need to allocate space for more than one element.
