[PATCH v3 2/5] EDAC/ghes: Cleanup struct dimm_fill

From: Robert Richter
Date: Tue May 19 2020 - 06:45:46 EST


The struct is used to store temporary data for the dmidecode callback.
Clean this up a bit:

1) Rename member count to index since this is what it is used for.

2) Move code close to ghes_edac_dmidecode() where it is used.

3) While at it, use edac_get_dimm_by_index().
