Subject: media: venus: pm_helpers: Set opp clock name for v1 Author: Stanimir Varbanov stanimir.varbanov@linaro.org Date: Thu Feb 25 15:28:57 2021 +0100

The rate of the core clock is set through devm_pm_opp_set_rate and to avoid errors from it we have to set the name of the clock via dev_pm_opp_set_clkname.
