Hello Stephen,
Thanks for the patch

Use platform_get_irq_optional() to avoid a noisy error message when the
irq isn't specified. The irq is definitely optional given that we only
care about errors that are -EPROBE_DEFER here.

Here the idea is to return only -EPROBE_DEFER error. Else return a 0 ,
so that cpufreq is enabled even if lmh interrupt is inaccessible. The
above check returns errors other than -EPROBE_DEFER as well. So I would
say make irq optional and keep the below check
if (data->throttle_irq <= 0)
return data->throttle_irq == -EPROBE_DEFER ? -EPROBE_DEFER : 0;
data->cancel_throttle = false;
data->policy = policy;
