fs/ext3/balloc.c: delete useless initialization
Julia Lawall [Thu, 4 Aug 2011 10:29:31 +0000 (12:29 +0200)]
Delete nontrivial initialization that is immediately overwritten by the
result of an allocation function.

The semantic match that makes this change is as follows:

// <smpl>

type T;
identifier i;
expression e;

(
T i = \(0\|NULL\|ERR_PTR(...)\);

-T i = e;
+T i;
)
... when != i
i = \(kzalloc\|kcalloc\|kmalloc\)(...);
