Subject: [PATCH] memory: tegra: Remove calls to dev_pm_opp_set_clkname()
Date: Fri, 22 Jan 2021 11:30:21 +0530 [thread overview]
Message-ID: <1430e70777fdcf1c946ca2fef296f439762a4f21.1611295029.git.viresh.kumar@linaro.org> (raw)
There is no point calling dev_pm_opp_set_clkname() with the "name"
parameter set to NULL, this is already done by the OPP core at setup
time and should work as it is.

Dmitry, am I missing something obvious here ?
