[Denys Vlasenko]

commit: https://git.busybox.net/busybox/commit/?id=2bbd1e1e8ababc480ff5d373847ab98ba0cc23dd
branch: https://git.busybox.net/busybox/commit/?id=refs/heads/master

cluster_count is compared against FAT16_MAX, which is defined as 0xfff4
That is the maximum number of cluster a FAT16 can have.
