Didn't we say that inject nodes should be in debugfs? So I'm going to stop looking here and wait for you to do the same changes to L3 and SOC as for the rest of the driver. Go through what just went upstream and do the same changes to that patch instead of blindly resending the original version. It is not a competition who gets their stuff upstream first, ok?! > +static int xgene_edac_l3_add(struct xgene_edac *edac, struct device_node *np) > +{ > + struct edac_device_ctl_info *edac_dev; > + struct xgene_edac_dev_ctx *ctx; > + struct resource res; > + int edac_idx; > + int rc = 0; > + > + if (!devres_open_group(edac->dev, xgene_edac_l3_add, GFP_KERNEL)) > + return -ENOMEM; > + > + edac_idx = edac_device_alloc_index(); > + edac_dev = edac_device_alloc_ctl_info(sizeof(*ctx), > + "l3c", 1, "l3c", 1, 0, NULL, 0, > + edac_idx); > + if (!edac_dev) { > + rc = -ENOMEM; > + goto err; > + } > + > + ctx = edac_dev->pvt_info; > + ctx->name = "xgene_l3_err"; > + ctx->edac_idx = edac_idx; > + ctx->edac = edac; > + ctx->edac_dev = edac_dev; > + ctx->ddev = *edac->dev; > + edac_dev->dev = &ctx->ddev; > + edac_dev->ctl_name = ctx->name; > + edac_dev->dev_name = ctx->name; > + edac_dev->mod_name = EDAC_MOD_STR; As before, do the allocation and preparation of edac_dev only after ... > + > + rc = of_address_to_resource(np, 0, &res); > + if (rc < 0) { > + dev_err(edac->dev, "no L3 resource address\n"); > + goto err1; > + } > + ctx->dev_csr = devm_ioremap_resource(edac->dev, &res); > + if (IS_ERR(ctx->dev_csr)) { > + dev_err(edac->dev, > + "devm_ioremap_resource failed for L3 resource address\n"); > + rc = PTR_ERR(ctx->dev_csr); > + goto err1; > + } ... those above have succeeded. > + > + if (edac_op_state == EDAC_OPSTATE_POLL) > + edac_dev->edac_check = xgene_edac_l3_check; > + > + edac_dev->sysfs_attributes = xgene_edac_l3_sysfs_attributes; > + > + rc = edac_device_add_device(edac_dev); > + if (rc > 0) { > + dev_err(edac->dev, "failed edac_device_add_device()\n"); > + rc = -ENOMEM; > + goto err1; > + } > + > + if (edac_op_state == EDAC_OPSTATE_INT) > + edac_dev->op_state = OP_RUNNING_INTERRUPT; > + > + list_add(&ctx->next, &edac->l3s); > + > + xgene_edac_l3_hw_init(edac_dev, 1); Shouldn't you init the hw regs *before* you add it to the list of l3s and *not* after?
