Subject: [Qemu-devel] [PATCH] spapr_vscsi: Set uninitialized variable
Date: Sun,  3 Apr 2011 18:21:24 +0200	[thread overview]
Message-ID: <1301847684-8125-1-git-send-email-weil@mail.berlios.de> (raw)

cppcheck reports this error:

hw/spapr_vscsi.c:274: error: Uninitialized variable: rc

If llen == 0, rc was indeed used without being initialized.
