Subject: hwmon: (ads1015) Fix out-of-bounds array access
From: Axel Lin <axel.lin@xxxxxxxxxx>
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.
