Subject: media: venus: pm_helpers: Set opp clock name for v1
Author: Stanimir Varbanov <stanimir.varbanov@xxxxxxxxxx>
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.
