Date: Wed, 3 Sep 2014 15:05:12 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Axel Lin <axel.lin@...ics.com>, Guenter Roeck <linux@...ck-us.net> Subject: [PATCH 3.10 22/55] hwmon: (ads1015) Fix out-of-bounds array access 3.10-stable 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.
