From mboxrd@z Thu Jan 1 00:00:00 1970 From: Axel Lin Date: Fri, 01 Aug 2014 02:03:09 +0000 Subject: [lm-sensors] [PATCH 1/2] hwmon: (ads1015) Fix out-of-bounds array access Message-Id: <1406858589.21842.2.camel@phoenix> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lm-sensors@vger.kernel.org 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. If the setting is out-of-range, don't apply it.
