device: Make dev_WARN/dev_WARN_ONCE print device as well as driver name
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().
