[PATCH 3/4] drivers/media/video/hexium_gemini.c: delete useless initialization

From: Julia Lawall
Date: Thu Aug 04 2011 - 06:30:32 EST


From: Julia Lawall <julia@xxxxxxx>

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>
