From 2e1a2556ebbbe7b53a05b721ac0d3d8ca9873cdb Mon Sep 17 00:00:00 2001 From: Andrew Donnellan Date: Tue, 13 Oct 2015 15:09:44 +1100 Subject: [PATCH] cxl: Free virtual PHB when removing When adding a vPHB in cxl_pci_vphb_add(), we allocate a pci_controller struct using pcibios_alloc_controller(). However, we don't free it in cxl_pci_vphb_remove(), causing a leak. Call pcibios_free_controller() in cxl_pci_vphb_remove() to free the vPHB data structure correctly.
