[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.
