Merge tag 'edac_updates_for_v6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras

Pull EDAC updates from Borislav Petkov:

 - The EDAC drivers part of the effort to make the ->remove() platform
   driver callback return void

 - Add support for AMD AI accelerators

 - Add support for a number of Intel SoCs: Alder Lake-N, Raptor Lake-P,
   Meteor Lake-{P,PS}

 - Random fixes and cleanups all over the place
