From 91b327f6728b0c4dfa089f11a474789854baa0b1 Mon Sep 17 00:00:00 2001 From: Robert Richter Date: Thu, 23 Jan 2020 09:02:56 +0000 Subject: [PATCH] EDAC/mc: Determine mci pointer from the error descriptor Each struct mci has its own error descriptor. Create a function error_desc_to_mci() to determine the corresponding mci from an error descriptor. This removes @mci from the parameter list of edac_raw_mc_handle_error() as the mci pointer does not need to be passed any longer.
