[PATCH 06/12] iio: pressure: rohm-bm1390: Return error when read fails

[Matti Vaittinen]

From: Matti Vaittinen <mazziesaccount@xxxxxxxxx>

The data reading function ignores the cached error value, and
unconditionally returns 0. Return cached 'ret' -value after stopping
the measurement so user knows if read failed and data is garbage.
