Those are terribly generic messages. I don't think I would have guessed
which device was trying to tell me "powered 1" if I found it in the
logs...
How about using e.g dev_dbg() to get a bit more context here?
You might also want to put all three into a single call, so that they
make a single dynamic debug entry when dynamic debugging is enabled.
And looking at toshiba_bluetooth_status() I see that all callers have a
device. How about propagating the device to be able to use the dev_*
printk's there as well? Let the device identify itself instead of
having to guess.
