Hi Seung-Woo,
> After the commit 265edc03d5a1 ("fs/fat: Clean up open-coded sector
> <-> cluster conversions"), it is hung up writing new file to FAT16
> disk with more than 19 files in armv7. It is because result value
> of sect_to_cluster() is not proper by casting from signed value to
> unsigned value. Fix the wrong casting of sect_to_cluster().
