This is confusing. Updated this as:

The OPP core already performs clk_get(dev, NULL) by default for everyone
and the callers shouldn't try to set clkname unless they have an actual
clock name to add here.

Sorry about that, it is clk_get() it performs from
_update_opp_table_clk().

I don't think you need to call devm_pm_opp_set_clkname() here, but
lets see if this breaks anything for you.
