Subject: [media] drivers/media/video/hexium_gemini.c: delete useless initialization
X-Git-Tag: next-20110927~67^2~4^2~171

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

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 = \(kzalloc\|kcalloc\|kmalloc\)(...);

// </smpl>
