[BusyBox-cvs] busybox/util-linux fdisk.c,1.16,1.17

[Erik Andersen]

Update of /var/cvs/busybox/util-linux
In directory nail:/tmp/cvs-serv19529/util-linux

Modified Files:
	fdisk.c 
Log Message:
Eliminate use of a kernel scsi header file.

Prevent potentially misaligned accesses while indexing a pointer
to the partition table, which would be a bad thing on i.e. arm.
