PM / Domains: pdd->dev can't be NULL in genpd_dev_pm_qos_notifier()

vireshk · rafaeljw · commit b4883ca44947 · 2017-06-22T03:13:08.000+02:00
The pm_domain_data (pdd) pointer is set from genpd_alloc_dev_data() and
pdd-&gt;dev is guaranteed to be valid. There is no need to check pdd and
pdd-&gt;dev in rest of the code as pdd-&gt;dev will always be valid for a non
NULL pdd pointer.
