This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows [1].
As the "chip" variable is a pointer to "struct mtk_nfc_nand_chip" and
this structure ends in a flexible array:
struct mtk_nfc_nand_chip {
[...]
u8 sels[] __counted_by(nsels);
};
the preferred way in the kernel is to use the struct_size() helper to
do the arithmetic instead of the argument "size + count * size" in the
devm_kzalloc() function.
This way, the code is more readable and safer.
