Subject: [PATCH 1/2] EDAC remove unneeded functions and add static
accessor
From: Adrian Bunk <bunk@...nel.org>
diff against 2.6.25-rc8-mm1
Collection of patches, merged into one, from Adrian that do the following:
1) This patch makes the following needlessly global functions static:
- edac_pci_get_log_pe()
- edac_pci_get_log_npe()
- edac_pci_get_panic_on_pe()
- edac_pci_unregister_sysfs_instance_kobj()
- edac_pci_main_kobj_setup()
2) Remove unneeded function edac_device_find()
3) Added #if 0 around function edac_pci_find()
4) make the needlessly global edac_pci_generic_check() static
5) Removed function edac_check_mc_devices()
Doug Thompson modified Adrian's patches, to bettern represent
the direction of EDAC, and make them one patch.
