Subject: [PATCH AUTOSEL 4.9 10/26] Bluetooth: Fix calculation of SCO handle for packet processing
Date: Sat, 11 Apr 2020 19:13:57 -0400 [thread overview]
Message-ID: <20200411231413.26911-10-sashal@kernel.org> (raw)
In-Reply-To: <20200411231413.26911-1-sashal@kernel.org>
From: Marcel Holtmann <marcel@holtmann.org>
[ Upstream commit debdedf2eb5a2d9777cabff40900772be13cd9f9 ]
When processing SCO packets, the handle is wrongly assumed as 16-bit
value. The actual size is 12-bits and the other 4-bits are used for
packet flags.
