Subject: edac: add more verbose debug info
From: Hitoshi Mitake <h.mitake@xxxxxxxxx>
A patch for making a debugging information more verbose for use in
development debugging.
By enabling the new option "More verbose debugging", information about
source file and line number will be added to debugging message.
This is sample output,
EDAC MC0: Giving out device to 'e7xxx_edac' 'E7205': DEV 0000:00:00.0
EDAC DEBUG: in drivers/edac/edac_pci.c, line at 48: edac_pci_alloc_ctl_info()
EDAC DEBUG: in drivers/edac/edac_pci.c, line at 334: edac_pci_add_device()
