[PATCH 2/2] video: delete unneeded call to platform_get_drvdata

From: Julia Lawall
Date: Sat May 17 2014 - 02:34:30 EST


From: Julia Lawall <Julia.Lawall@xxxxxxx>

Platform_get_drvdata is an accessor function, and has no purpose if its
result is not used.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
identifier x;
type T;
@@
- T x = platform_get_drvdata(...);
... when != x
// </smpl>
