From cd725bd7489e52445a15dd2f0ad1aa746dfa91fc Mon Sep 17 00:00:00 2001 From: Greg Kurz Date: Fri, 18 Dec 2020 11:33:55 +0100 Subject: spapr: Call spapr_drc_reset() for all DRCs at CAS Non-transient DRCs are either in the empty or the ready state, which means spapr_drc_reset() doesn't change their state. It is thus not needed to do any checking. Call spapr_drc_reset() unconditionally and squash spapr_drc_transient() into its only user, spapr_drc_needed().
