| |
From: Julia Lawall <julia@diku.dk>
Delete nontrivial initialization that is immediately overwritten by the result of an allocation function.
The semantic match that makes this change is as follows: (http://coccinelle.lip6.fr/)
// <smpl> @@ type T; identifier i; expression e; @@
( T i = \(0\|NULL\|ERR_PTR(...)\); | -T i = e; +T i; ) ... when != i i = \(kzalloc\|kcalloc\|kmalloc\)(...);
// </smpl>
