One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct ioat_dca_priv {
...
struct ioat_dca_slot req_slots[0];
};
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.
So, replace the following form:
sizeof(*ioatdca) + (sizeof(struct ioat_dca_slot) * slots)
with:
struct_size(ioatdca, req_slots, slots)
