You likely can use coccinelle to find these. It works better than grep.
Everything is probably better than grep in this case. I actually used weggli to find those malloc/memset uses.
I was actually thinking if something about the calloc implementation could bite us if we just change all malloc/memset occurances to calloc. Something similar to what is described in this article for example:
