[PATCH] Driver Core: Make dev_info and friends print the bus name if there is no driver

Browse Source 
This patch (as721) makes dev_info and related macros print the device's
bus name if the device doesn't have a driver, instead of printing just a
blank.  If the device isn't on a bus either... well, then it does leave
a blank space.  But it will be easier for someone else to change if they
want.
