>From 5f63649f0084b72d76d95ffafde45ad06bd84b49 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra <peterz@xxxxxxxxxxxxx> Date: Mon, 30 Apr 2018 12:00:11 +0200 Subject: [PATCH] clocksource: Initialize cs->wd_list commit 5b9e886a4af97574ca3ce1147f35545da0e7afc7 upstream A number of places relies on list_empty(&cs->wd_list), however the list_head does not get initialized. Do so upon registration, such that thereafter it is possible to rely on list_empty() correctly reflecting the list membership status.
