Subject: [PATCH 8/42] drivers/net/ixgbe: Adjust confusing if indentation

From: Julia Lawall <julia@...u.dk>

Both ifs and assignments to autoc seem similar enough that they are both
put in the if branch indicated by their indentation.

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>

Signed-off-by: Julia Lawall <julia@...u.dk>

This changes the semantics and might be the wrong fix.  Not tested.
