drivers/staging: delete double assignment
Delete successive assignments to the same location. In three of the cases,
the two assignments are identical. In the case of the file
rt2860/common/cmm_aes.c, the assigned variable i is never used, so both
assignments are dropped.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression i;
@@
*i = ...;
i = ...;
// </smpl>
