Subject: [PULL 26/54] ppc/pnv: Fix check on block device before updating drive contents
Date: Tue, 9 Nov 2021 16:51:36 +1100 [thread overview]
Message-ID: <20211109055204.230765-27-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20211109055204.230765-1-david@gibson.dropbear.id.au>
From: Cédric Le Goater <clg@kaod.org>
Test is wrong and the backend can never updated. It could have led to
a QEMU crash but since the firmware deactivates flash access if a valid
layout is not detected, it went unnoticed.
Reported-by: Coverity CID 1465223
Fixes: 35dde5766211 ("ppc/pnv: Add a PNOR model")
