Commit Message

Stanimir Varbanov March 8, 2021, 10:52 a.m. UTC
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.

Fixes: 9a538b83612c ("media: venus: core: Add support for opp tables/perf voting")
Cc: stable@vger.kernel.org # v5.10+
