From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>
Update config space save/restore debug messages so they line up better.
Previously:
nvme 0000:05:00.0: saving config space at offset 0x4 (reading 0x20100006)
nvme 0000:05:00.0: saving config space at offset 0x8 (reading 0x1080200)
nvme 0000:05:00.0: saving config space at offset 0xc (reading 0x0)
nvme 0000:05:00.0: restoring config space at offset 0x4 (was 0x0, writing 0x20100006)
Now:
nvme 0000:05:00.0: save config 0x04: 0x20100006
nvme 0000:05:00.0: save config 0x08: 0x01080200
nvme 0000:05:00.0: save config 0x0c: 0x00000000
nvme 0000:05:00.0: restore config 0x04: 0x00000000 -> 0x20100006
No functional change intended. Enable these messages by setting
CONFIG_DYNAMIC_DEBUG=y and adding 'dyndbg="file drivers/pci/* +p"'
to kernel parameters.
