[PATCH 1/2] hw/pci/pci_host: Remove redundant PCI_DPRINTF() |
Date: |
Mon, 16 Dec 2019 01:21:33 +0100 |
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.
