Merge tag 'edac_urgent_for_v5.9_rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras

Pull EDAC fixes from Borislav Petkov:
 "Two fixes for resulting from CONFIG_DEBUG_TEST_DRIVER_REMOVE=y
  experiments:

   - complete a previous fix to reset a local structure containing
     scanned system data properly so that the driver rescans, as it
     should, on a second load.

   - address a refcount underflow due to not paying attention to the
     driver whitelest on unregister"
