https://patchwork.ozlabs.org/patch/529548/ - cxl: Free virtual PHB when removing

Andrew Donnellan - Sept. 10, 2015, 6:28 a.m.
1)  Export pcibios_free_controller(), so it can be used by the cxl module to
free virtual PHBs.

2) 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.
