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

From: Christophe Jaillet <jaillet.christophe@...adoo.fr>

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.

It is the same patch as the one I sent earlier but the formating should be OK this time.
