2011-05-05MSI: Robust resource releaseJan Kiszka1-2/+10
msi_init may fail, so we need to check on uninit if the cap was actually installed. This also avoids that the users need to check. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2010-10-27msi: simplify range checksMichael S. Tsirkin1-25/+20
config write handlers should be idempotent. So no need for complex range checks: a simple one checking that we are touching the relevant capability will do. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
