Subject: [PATCH v2 1/3] Bluetooth: btusb: fix wakeup source leak on probe failure
Date: Thu, 2 Apr 2026 11:27:02 +0200 [thread overview]
Message-ID: <20260402092704.2346710-2-johan@kernel.org> (raw)
In-Reply-To: <20260402092704.2346710-1-johan@kernel.org>
Make sure to disable wakeup on probe failure to avoid leaking the wakeup
source.
Fixes: fd913ef7ce61 ("Bluetooth: btusb: Add out-of-band wakeup support")
