Subject: [PATCH 1/5] interconnect: qcom: sdm845: Walk the list safely on node removal
Date:   Thu, 28 Nov 2019 15:34:31 +0200
Message-Id: <20191128133435.25667-1-georgi.djakov@linaro.org>
MIME-Version: 1.0

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

As we will remove items off the list using list_del(), we need to use the
safe version of list_for_each_entry().
