c44696ff ("EDAC: Remove arbitrary limit on number of channels") lifted the arbitrary limit on memory controller channels in EDAC. However, the dynamic channel attributes dynamic_csrow_dimm_attr and dynamic_csrow_ce_count_attr remained 6. This wasn't a problem except channels 6 and 7 weren't visible in sysfs on machines with more than 6 channels after the conversion to static attr groups with 2c1946b6 ("EDAC: Use static attribute groups for managing sysfs entries") [ without that, we're exploding in edac_create_sysfs_mci_device() because we're dereferencing out of the bounds of the dynamic_csrow_dimm_attr array. ] Add attributes for channels 6 and 7 along with a guard for the future, should more channels be required and/or to sanity check for misconfigured machines. We still need to check against the number of channels present on the MC first, as Thor reported.
