Add a check for ResourcePaddingDescriptors being a valid pointer in DumpPpbPaddingResource() to prevent looping on memory not owned by PciBusDxe. The ResourcePaddingDescriptors is initialized to NULL when the PCI_IO_DEVICE structure is allocated and remains NULL if no PCI hot plug controllers are present. This issue is only observed when DEBUG_CODE() macros are enabled and was introduced by the following patch: [edk2] [Patch] MdeModulePkg: Fix a PciBusDxe hot plug bug SVN revsion 18658 Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Ruiyu Ni <ruiyu.ni@intel.com> Reviewed-by: Feng Tian <feng.tian@intel.com> Reviewed-by: Kinney Michael <michael.d.kinney@intel.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@18696 6f19259b-4bc3-4df7-8a09-765794883524
