Hello Rob Herring,
The patch d1552ce449eb: "of/fdt: move memreserve and dtb memory
reservations into core" from Apr 1, 2014, leads to the following
static checker warning:
drivers/of/fdt.c:594 early_init_fdt_scan_reserved_mem()
error: potentially using uninitialized 'size'.
drivers/of/fdt.c
583 void __init early_init_fdt_scan_reserved_mem(void)
584 {
585 int n;
586 u64 base, size;
^^^^
587
588 if (!initial_boot_params)
589 return;
590
591 /* Process header /memreserve/ fields */
592 for (n = 0; ; n++) {
593 fdt_get_mem_rsv(initial_boot_params, n, &base, &size);
^^^^
594 if (!size)
^^^^
Presumably we don't care about errors during boot because it's doomed
anyway, but we might want to silence the warning?
595 break;
596 early_init_dt_reserve_memory_arch(base, size, 0);
597 }
598
599 of_scan_flat_dt(__fdt_scan_reserved_mem, NULL);
600 fdt_init_reserved_mem();
601 }
regards,
dan carpenter
