File flashrom.c:

PS24, Line 1088: 	for (i = 0; i < NUM_ERASEFUNCTIONS; i++) {
Suggestion:

```
for (int i = 0; check_block_eraser(flashctx, i, 0) == 0, i++) {
  struct block_eraser eraser = flash->chip->block_erasers[i];
  ...
  while(addr < chip->total_size * 1024) {
    block_count += erasers.eraseblocks[j].count;
    addr += erasers.eraseblocks[j].size * erasers.eraseblocks[j].count;
  }
}
```
So you have only one array index at a time in a loop.
