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(*ce_hdr) + CE_COUNT * sizeof(ce_hdr->entries[0])
with:
struct_size(ce_hdr, entries, CE_COUNT)
This code was detected with the help of Coccinelle.
