If walk_system_ram_range() reports more than\n16 memory ranges, the overflow call writes one struct maar_config past\nthe end of the array before WARN_ON() prevents num_cfg from advancing.\n\nMove the full-array check before taking the array slot and return non-zero\nwhen the scratch array is full, so walk_system_ram_range() terminates the\nwalk instead of invoking the callback for further ranges."
