Vaibhav Jain 5fc8d62d19 cxl: Check if vphb exists before iterating over AFU devices ... commit 12841f87b7a8ceb3d54f171660f72a86941bfcb3 upstream. During an eeh a kernel-oops is reported if no vPHB is allocated to the AFU. This happens as during AFU init, an error in creation of vPHB is a non-fatal error. Hence afu->phb should always be checked for NULL before iterating over it for the virtual AFU pci devices. This patch fixes the kenel-oops by adding a NULL pointer check for afu->phb before it is dereferenced.
