This fixes a sparse warning in the hardware-TKIP code:
drivers/net/wireless/b43/xmit.c:272:18: warning: incorrect type in assignment (different base types)
drivers/net/wireless/b43/xmit.c:272:18: expected unsigned short [unsigned] [short] <noident>
drivers/net/wireless/b43/xmit.c:272:18: got restricted unsigned short [usertype] <noident>
The code should work correctly with and without this patch applied.
