Subject: [PATCH 3/8] drm/msm: Unconditionally call dev_pm_opp_of_remove_table()
Date: Thu, 20 Aug 2020 16:13:52 +0530	[thread overview]
Message-ID: <4ca1dd576f016d49e57b679d0921a268b4a7fa62.1597919647.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1597919647.git.viresh.kumar@linaro.org>

dev_pm_opp_of_remove_table() doesn't report any errors when it fails to
find the OPP table with error -ENODEV (i.e. OPP table not present for
the device). And we can call dev_pm_opp_of_remove_table()
unconditionally here.
