Date: Sun, 17 Apr 2011 08:22:21 -0700 From: Greg Thelen <gthelen@...gle.com> To: Jesse Barnes <jbarnes@...tuousgeek.org> Cc: linux-pci@...r.kernel.org, linux-kernel@...r.kernel.org, Greg Thelen <gthelen@...gle.com> 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.
