From 271ced1d62e0c46089fab47c8560c4e550806d69 Mon Sep 17 00:00:00 2001 From: Greg Kurz Date: Mon, 19 Oct 2020 10:48:41 +0200 Subject: [PATCH] spapr: Pass &error_abort when getting some PC DIMM properties Both PC_DIMM_SLOT_PROP and PC_DIMM_ADDR_PROP are defined in the default property list of the PC DIMM device class: DEFINE_PROP_UINT64(PC_DIMM_ADDR_PROP, PCDIMMDevice, addr, 0), DEFINE_PROP_INT32(PC_DIMM_SLOT_PROP, PCDIMMDevice, slot, PC_DIMM_UNASSIGNED_SLOT), They should thus be always gettable for both PC DIMMs and NVDIMMs. An error in getting them can only be the result of a programming error. It doesn't make much sense to propagate the error in this case. Abort instead.
