From 9816b4af4351bf9d33c2e635b6f14327823a9c2a Mon Sep 17 00:00:00 2001 From: Hanna Hawa Date: Mon, 23 Sep 2019 20:17:40 +0100 Subject: EDAC/device: Rework error logging API Make the main workhorse the "count" functions which can log a @count of errors. Have the current APIs edac_device_handle_{ce,ue}() call the _count() variants and this way keep the exported symbols number unchanged.
