Subject: [PATCH v5 3/4] PCI: qcom-ep: Update the D-state log
Date:   Wed,  2 Aug 2023 09:21:20 +0530
Message-Id: <1690948281-2143-4-git-send-email-quic_krichai@quicinc.com>
In-Reply-To: <1690948281-2143-1-git-send-email-quic_krichai@quicinc.com>
References: <1690948281-2143-1-git-send-email-quic_krichai@quicinc.com>
Precedence: bulk

Now that the state event is stored as pci_power_t, let's use the PCI helper
pci_power_name() to print the state event.
