[PATCH 05/13] Bluetooth: Remove unnecessary indentation in unpair_device()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Johan Hedberg <johan.hedberg@xxxxxxxxx>

Instead of doing all of the LE-specific handling in an else-branch in
unpair_device() create a 'done' label for the BR/EDR branch to jump to
and then remove the else-branch completely.
