[PATCH v2 1/2] PCI: Log device readiness timeouts as errors

[Bjorn Helgaas <helgaas@kernel.org>]

pci_dev_wait() waits for a device to be Configuration-Ready after a reset,
such as a Function-Level Reset (FLR), a soft reset during a D3hot->
D0uninitialized transition when No_Soft_Reset == 0), or a power-up sequence
from D3cold->D0uninitialized.

If pci_dev_wait() returns success, the device is guaranteed to respond to
configuration requests with Successful Completion status.  If it times out,
device is completely non-responsive.

Upgrade the log level from pci_warn() to pci_err() to reflect this failure
state.
