- * edac_align_ptr - Prepares the pointer offsets for a single-shot allocation

- *             return, this will be incremented to point to the next offset
- * @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.
