This patch fixes sysfs exit code for the EDAC PCI device in a similiar manner and the previous fixes for EDAC_MC and EDAC_DEVICE. It removes the old (and incorrect) completion model and uses reference counts on per instance kobjects and on the edac core module. This pattern was applied to the edac_mc and edac_device code, but the EDAC PCI code was missed. In addition, this fixes a system hang after a low level driver was unloaded. (A cleanup function was called twice, which really screwed things up) Cc: Greg KH <greg@kroah.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Doug Thompson <dougthompson@xmission.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
