Subject: [PATCH] sample: vfio mdev display - Fix a missing error code in an error handling path
Date: Mon, 16 Sep 2019 22:22:40 +0200 [thread overview]
Message-ID: <20190916202240.30189-1-christophe.jaillet@wanadoo.fr> (raw)
'ret' is known to be 0 at this point. So explicitly set it to -ENOMEM if
'framebuffer_alloc()' fails.
