[PATCH] drivers/pcmcia/cistpl.c: introduce missing braces

[Julia Lawall]

From: Julia Lawall <julia at diku.dk>

The indentation and behavior of the code below suggests that braces are
intended around the if branch.

The semantic match that finds the problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@r exists@
local idexpression x;
statement S;
expression E;
identifier f,l;
position p1,p2;
expression *ptr != NULL;
@@

(
if ((x at p1 = \(kmalloc\|kzalloc\|kcalloc\)(...)) == NULL) S
|
x at p1 = \(kmalloc\|kzalloc\|kcalloc\)(...);
...
if (x == NULL) S
)
<... when != x
     when != if (...) { <+...x...+> }
x->f = E
...>
(
 return \(0\|<+...x...+>\|ptr\);
|
 return at p2 ...;
)

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

print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line)
// </smpl>
