Subject: [PATCH 1/8] Bluetooth: Remove pointless parameter check in bfusb_send_frame()
Date: Fri, 11 Oct 2013 07:00:57 -0700	[thread overview]
Message-ID: <1381500064-24414-2-git-send-email-marcel@holtmann.org> (raw)

The hdev parameter of bfusb_send_frame() is always valid. If it were
not valid, then it would have crashed earlier in the call chain.
