Assignments should not happen inside an if conditional, but in the line
before. This issue was reported by checkpatch.

The semantic patch that makes this change is as follows
(http://coccinelle.lip6.fr/):

// <smpl>

@@
identifier i1;
expression e1;
statement S;
@@
-if(!(i1 = e1)) S
+i1 = e1;
+if(!i1)
+S

// </smpl>

It has been tested by compilation.
