Initialize retval before returning from a failed call to ioremap.
A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/)
// <smpl> ( if@p1 ((ret < 0|ret != 0)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; }
// </smpl>
