Will be used to more cleanly implement existing method interfaces that take some confusing (IEDTkey, inherited from VBIOS, which RM no longer uses on Ampere) match values to determine which display path to operate on. Methods will be protected from racing with supervisor, and from being called where they shouldn't be (ie. without an OR assigned). v2: - use ?: (lyude) v3: - fix return code if noacquire() method fails Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
