[PATCH 4/5] drivers/staging/otus: drop redundant memset

[Julia Lawall <julia@xxxxxxx>]

From: Julia Lawall <julia@xxxxxxx>

The region set by the call to memset is immediately overwritten by the
subsequent call to memcpy.

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

// <smpl>
@@
expression e1,e2,e3,e4;
@@

- memset(e1,e2,e3);
  memcpy(e1,e4,e3);
// </smpl>
