From 318347234d7069b62d38391dd27e269a3107d668 Mon Sep 17 00:00:00 2001 From: Daniel Henrique Barboza Date: Mon, 22 May 2017 16:35:48 -0300 Subject: hw/ppc: removing drc->detach_cb and drc->detach_cb_opaque The pointer drc->detach_cb is being used as a way of informing the detach() function inside spapr_drc.c which cb to execute. This information can also be retrieved simply by checking drc->type and choosing the right callback based on it. In this context, detach_cb is redundant information that must be managed. After the previous spapr_lmb_release change, no detach_cb_opaques are being used by any of the three callbacks functions. This is yet another information that is now unused and, on top of that, can't be migrated either. This patch makes the following changes: - removal of detach_cb_opaque. the 'opaque' argument was removed from the callbacks and from the detach() function of sPAPRConnectorClass. The attribute detach_cb_opaque of sPAPRConnector was removed. - removal of detach_cb from the detach() call. The function pointer detach_cb of sPAPRConnector was removed. detach() now uses a switch(drc->type) to execute the apropriate callback. To achieve this, spapr_core_release, spapr_lmb_release and spapr_phb_remove_pci_device_cb callbacks were made public to be visible inside detach().
