Seems like you're introducing an unnecessary empty line above.

We usually check for valid timeout or GSource IDs with id > 0.

This last btdev = NULL is pointless since you're leaving the function
and the variable goes out of scope.

Iterating data->iter and i++ throughout the entire loop seems overkill
I'd just assign the resulting value of i to data->iter once you've
exited to loop.

I'd prefer if we can make this so that you instead have the timeout
called as many times as necessary and send just one event each time.
I.e. upon reception of HCI_Inquiry you check the duration of the
inquiry, the maximum amount of responses, MAX_BTDEV_ENTRIES and
determine how frequently the timeout should be called in order to send
all events by the time the inquiry should complete.

We usually use "failed" for this kind of labels.

This looks like possibly incorrect indentation. The indentation should
go past the opening ( and then have more lines if necessary.
