[PATCH 1/1] drivers/block/pktcdvd.c : avoid useless memset

[JAILLET]

From: Christophe Jaillet <jaillet.ïchristophe@xxxxxxxxxx>

Hi, here is a patch against linux/drivers/block/pktcdvd.c which :

1) Avoid to 'memset(...,0, ...)' before calling 'init_cdrom_command' 
because this function already does it.
