* @size: Size of the data structure to be reserved
* @n_elems: Number of elements that should be reserved
*
* If 'size' is a constant, the compiler will optimize this whole function
* down to either a no-op or the addition of a constant to the value of '*p'.
*
* The 'p' pointer is absolutely needed to keep the proper advancing
* further in memory to the proper offsets when allocating the struct along
* with its embedded structs, as edac_device_alloc_ctl_info() does it
* above, for example.
*
* At return, the pointer 'p' will be incremented to be used on a next call
* to this function.
