From d97ecd819137118b4686a753415f93215a6edacf Mon Sep 17 00:00:00 2001 From: Greg Thelen Date: Sun, 17 Apr 2011 08:22:21 -0700 Subject: [PATCH] PCI: check pci_vpd_pci22_wait() return pci_vpd_pci22_write() calls pci_vpd_pci22_wait() after writing PCI_VPD_DATA and PCI_VPD_ADDR to wait for the VPD operation to complete. The result pci_vpd_pci22_wait() was not checked for error. This change checks for error.
