This was really dumb - reference counting for the main EDAC sysfs object. While we could've simply registered it as the first thing in the module init path and then hand it around to what needs it. Do that and rip out all the code around it, thus simplifying the whole handling significantly. Move the edac_subsys node back to edac_module.c. Signed-off-by: Borislav Petkov <bp@suse.de>
