[PATCH 1/3] Bluetooth: Fix missing hci_dev_lock_bh in user_confirm_reply

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

 



From: Johan Hedberg <johan.hedberg@xxxxxxxxx>

The code was correctly calling _unlock at the end of the function but
there was no actual _lock call anywhere.
