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 MR_PD_CFG_SEQ_NUM_SYNC {
...
struct MR_PD_CFG_SEQ seq[1];
} __packed;
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(struct MR_PD_CFG_SEQ_NUM_SYNC) + (sizeof(struct MR_PD_CFG_SEQ) * (MAX_PHYSICAL_DEVICES - 1))
with:
struct_size(pd_sync, seq, MAX_PHYSICAL_DEVICES - 1)
