Subject: drivers/mmc: move a dereference below a NULL test
From: Julia Lawall <julia@xxxxxxx>
In each case, if the NULL test is necessary, then the dereference should be
moved below the NULL test.
The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>

type T;
expression E;
identifier i,fld;
statement S;
@@
- T i = E->fld;
+ T i;
... when != E
when != i
if (E == NULL) S
+ i = E->fld;
// </smpl>
