[PATCH 22/42] drivers/scsi/lpfc: Adjust confusing if indentation

[Julia Lawall]

From: Julia Lawall <julia@xxxxxxx>

In lpfc_init.c, the call to lpfc_destroy_vport_work_array only has an
effect if vports is not NULL, so move it into the if branch that it is
already aligned with.

In lpfc_vport.c, ndlp has already been tested, so it is only useful to test
it again in the if branch that it is already aligned with.

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>
