mtd: spear_smi: failure test for null rather than negative integer
dev_get_platdata returns a pointer, so the failure value would be NULL
rather than a negative integer.
The semantic match that finds this problem is: (http://coccinelle.lip6.fr/)
// <smpl>

expression x,e;
statement S1,S2;

*x = dev_get_platdata(...)
... when != x = e
*if (x < 0) S1 else S2
