Subject: drivers/platform/x86: Adjust confusing if indentation

drivers/platform/x86: Adjust confusing if indentation

The assignment of ret to -EIO appears to only make sense if the branch that
it is aligned with is executed, so move it into that branch.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r disable braces4@
position p1,p2;
statement S1,S2;
@@

(
if (...) { ... }
|
if (...) S1@p1 S2@p2
)

@script:python@
p1 << r.p1;
p2 << r.p2;
@@

if (p1[0].column == p2[0].column):
  cocci.print_main("branch",p1)
  cocci.print_secs("after",p2)
// </smpl>
