Subject: [PATCH 1/2] hw/pci/pci_host: Remove redundant PCI_DPRINTF()
Date: Mon, 16 Dec 2019 01:21:33 +0100	[thread overview]
Message-ID: <20191216002134.18279-2-philmd@redhat.com> (raw)
In-Reply-To: <20191216002134.18279-1-philmd@redhat.com>

In commit 3bf4dfdd111 we introduced the pci_cfg_[read/write]
trace events in pci_host_config_[read/write]_common().
We have the following call trace:

  pci_host_data_[read/write]()
    - PCI_DPRINTF()
    - pci_data_[read/write]()
        - PCI_DPRINTF()
        - pci_host_config_[read/write]_common()
            trace_pci_cfg_[read/write]()

Since the PCI_DPRINTF() calls are redundant with the trace
events, remove them.
