[Romit] I think this should be done outside this function, in
update_resource_level function.

[Romit] Shouldn't the following line execute only if pm_qos_add_requirement
returns successfully?

[Romit] Again is this the right place for this? It should be done only if
set_pwrdm_state returns successfully. So I think that should be checked as well.
