No need to put bit clearing inside the loop, something like below would
be slightly better.

if (chip->flags & AT24_FLAG_ADDR16)
	dev_warn(dev, "address-width is 8, clear the ADDR16 bit\n");
chip->flags &= ~AT24_FLAG_ADDR16;

On top of this the message would sound clearer if you put it like

"Override address width to be 8, while default is 16"
