> "hsi2c_pclk" clock is optional and may not be present for some SoCs
> supported by this driver. Nevertheless, in case the clock is provided but
> some error happens during its getting, that error should be handled
> properly. Use devm_clk_get_optional() API for that. Also report possible
> errors using dev_err_probe() to handle properly -EPROBE_DEFER error (if
> clock provider is not ready by the time I2C probe function is executed).
