From ad4050dcda135548477c1b04909f9ebd0b9e17ba Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Wed, 30 May 2018 11:52:16 -0500 Subject: [PATCH] PCI/AER: Remove aer_recover_work_func() forward declaration Just move the actual function up so that it is visible to its user aer_recover_queue(). No functional changes.
