Subject: [PATCH 14/14] drivers/ata/pata_octeon_cf.c: delete double assignment

From: Julia Lawall <julia@...u.dk>

Delete successive assignments to the same location.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression i;
@@

*i = ...;
 i = ...;
// </smpl>
