Staging: otus: drop redundant memset
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> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
