Subject: [PATCH 2/2] si2157: Bounds check firmware
To: Antti Palosaari <crope@iki.fi>

Cc: Olli Salonen <olli.salonen@iki.fi>

Cc: linux-kernel@vger.kernel.org
When reading the firmware and sending commands, the length
must be bounds checked to avoid overrunning the size of the command
buffer and smashing the stack if the firmware is not in the
expected format. Add the proper check.
