[PATCH] pm: print name of failed suspend function
Print more diagnostic info to help identify the source of power management suspend failures. Example: usb_hcd_pci_suspend(): pci_set_power_state+0x0/0x1af() returns -22 pci_device_suspend(): usb_hcd_pci_suspend+0x0/0x11b() returns -22 suspend_device(): pci_device_suspend+0x0/0x34() returns -22 Work-in-progress. It needs lots more suspend_report_result() calls sprinkled everywhere.
