Message-Id: <20151106192207.205575579@linuxfoundation.org> Date: Fri, 6 Nov 2015 11:22:36 -0800 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Dan Carpenter <dan.carpenter@...cle.com>, Jonathan Cameron <jic23@...nel.org> Subject: [PATCH 4.1 37/86] iio: accel: sca3000: memory corruption in sca3000_read_first_n_hw_rb() 4.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Dan Carpenter <dan.carpenter@...cle.com> commit eda7d0f38aaf50dbb2a2de15e8db386c4f6f65fc upstream. "num_read" is in byte units but we are write u16s so we end up write twice as much as intended.
