[PATCH 08/10] EDAC/mc: Pass the error descriptor to error reporting functions

From: Robert Richter
Date: Wed Nov 27 2019 - 16:55:32 EST


Most arguments of error reporting functions are already stored in
struct edac_raw_error_desc error descriptor. Pass the error descriptor
to the functions and reduce the functions' arg list.
