Merge tag 'edac_urgent_for_v7.3_rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras

Pull EDAC fix from Borislav Petkov:

 - A single fix to altera_edac to use the proper objects when performing
   managed device operations instead of using temporary shallow struct
   copies which can cause dangling list pointers and havoc eventually

* tag 'edac_urgent_for_v7.3_rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras:
