Subject: [PATCH v6 3/4] PCI: qcom-ep: Print D-state name to distinguish D3hot/D3cold
Date: Fri, 8 Sep 2023 12:23:37 +0530 [thread overview]
Message-ID: <20230908-dstate_change-v6-3-b414a6edd765@quicinc.com> (raw)
In-Reply-To: <20230908-dstate_change-v6-0-b414a6edd765@quicinc.com>
Now that the state event is stored as pci_power_t, use the PCI helper
pci_power_name() to print the state event.
