Subject: [PATCH] iio: humidity: dht11: Allow non-zero decimals
|
|
|
|
The DHT11 datasheet is pretty cryptic, but it does suggest that after
|
|
each integer value (humidity and temperature) there are "decimal"
|
|
values. Validate these as integers in the range 0-9 and treat them as
|
|
tenths of a unit.
