From c4cf3b454ecaa222aad9017932bd3b9c9325d931 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Mon, 30 Nov 2015 19:02:01 +0100 Subject: EDAC: Rework workqueue handling Hide the EDAC workqueue pointer in a separate compilation unit and add accessors for the workqueue manipulations needed. Remove edac_pci_reset_delay_period() which wasn't used by anything.
