Subject: [PATCH - for v5.7 stable] opp: Put opp table in dev_pm_opp_set_rate() for empty tables
Date: Mon, 24 Aug 2020 15:00:03 +0530 [thread overview]
Message-ID: <e7e9f887328c06800a79f3b48feb623fd15aa3d5.1598261323.git.viresh.kumar@linaro.org> (raw)
From: Stephen Boyd <swboyd@chromium.org>
commit 8979ef70850eb469e1094279259d1ef393ffe85f upstream.
We get the opp_table pointer at the top of the function and so we should
put the pointer at the end of the function like all other exit paths
from this function do.
Cc: v5.7+ <stable@vger.kernel.org> # v5.7+
Fixes: aca48b61f963 ("opp: Manage empty OPP tables with clk handle")
