Yuezhang Mo 70465acbb0 exfat: fix exfat_find_empty_entry() not returning error on failure ... On failure, "dentry" is the error code. If the error code indicates that there is no space, a new cluster may need to be allocated; for other errors, it should be returned directly. Only on success, "dentry" is the index of the directory entry, and it needs to be converted into the directory entry index within the cluster where it is located.
