hwmon: (ads1015) Fix out-of-bounds array access

2014-08-06T00:49:01+00:00

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.

0 .. ADS1015_CHANNELS - 1.

drivers/hwmon/ads1015.c: In function 'show_in':

into mV.
