dev_WARN() and dev_WARN_ONCE() are annoying because (1) they include
only the driver name, not the device name, and (2) they print a spurious
newline in the middle.  This results in messages like this that are less
useful than they should be:

  [   40.094995] Device pcieport
  disabling already-disabled device

This patch makes them work more like dev_printk().
