Message-ID: <lsq.1410438733.478628018@decadent.org.uk> Date: Thu, 11 Sep 2014 13:32:13 +0100 From: Ben Hutchings <ben@...adent.org.uk> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org CC: akpm@...ux-foundation.org, "Axel Lin" <axel.lin@...ics.com>, "Guenter Roeck" <linux@...ck-us.net> Subject: [PATCH 3.2 056/131] hwmon: (ads1015) Fix out-of-bounds array access 3.2.63-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Axel Lin <axel.lin@...ics.com> commit e981429557cbe10c780fab1c1a237cb832757652 upstream. Current code uses data_rate as array index in ads1015_read_adc() and uses pga as array index in ads1015_reg_to_mv, so we must make sure both data_rate and pga settings are in valid value range. Return -EINVAL if the setting is out-of-range.
