[PATCH 5.12 354/384] media: venus: pm_helpers: Set opp clock name for v1

[Greg Kroah-Hartman]

From: Stanimir Varbanov <stanimir.varbanov@xxxxxxxxxx>

commit 3215887167af7db9af9fa23d61321ebfbd6ed6d3 upstream.

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")
