Staging: otus: drop redundant memset
Author: Julia Lawall <julia@diku.dk>
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/)
//
@@
expression e1,e2,e3,e4;
@@
- memset(e1,e2,e3);
memcpy(e1,e4,e3);
//
