Subject: [Intel-gfx] [PATCH v2 02/14] vfio/mbochs: Fix missing error unwind in mbochs_probe()
Date: Tue, 20 Jul 2021 14:42:48 -0300 [thread overview]
Message-ID: <2-v2-b6a5582525c9+ff96-vfio_reflck_jgg@nvidia.com> (raw)
In-Reply-To: <0-v2-b6a5582525c9+ff96-vfio_reflck_jgg@nvidia.com>
Compared to mbochs_remove() two cases are missing from the
vfio_register_group_dev() unwind. Add them in.
Fixes: 681c1615f891 ("vfio/mbochs: Convert to use vfio_register_group_dev()")
Reported-by: Cornelia Huck <cohuck@redhat.com>
