EDAC: Introduce an mci_for_each_dimm() iterator
Introduce an mci_for_each_dimm() iterator. It returns a pointer to a struct dimm_info. This makes the declaration and use of an index obsolete and avoids access to internal data of struct mci (direct array access etc). [ bp: push the struct dimm_info *dimm; declaration into the CONFIG_EDAC_DEBUG block. ] Signed-off-by: Robert Richter <rrichter@marvell.com> Signed-off-by: Borislav Petkov <bp@suse.de> Reviewed-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> Cc: "linux-edac@vger.kernel.org" <linux-edac@vger.kernel.org> Cc: James Morse <james.morse@arm.com> Cc: Tony Luck <tony.luck@intel.com> Link: https://lkml.kernel.org/r/20191106093239.25517-4-rrichter@marvell.com
