Subject: [PATCH 3/5] interconnect: qcom: msm8974: Walk the list safely on node removal
Date: Thu, 28 Nov 2019 15:34:33 +0200	[thread overview]
Message-ID: <20191128133435.25667-3-georgi.djakov@linaro.org> (raw)
In-Reply-To: <20191128133435.25667-1-georgi.djakov@linaro.org>

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

Fixes: 4e60a9568dc6 ("interconnect: qcom: add msm8974 driver")
Reported-by: Dmitry Osipenko <digetx@gmail.com>
