[PATCH v1 1/1] iio: fix center temperature of bmc150-accel-core

[PATCH v1 1/1] iio: fix center temperature of bmc150-accel-core

[Pascal Bouwmann]

The center temperature of the supported devices stored in the constant
BMC150_ACCEL_TEMP_CENTER_VAL is not 24 degrees but 23 degrees.

In the datasheet of the BMC150 device the center temperature is given
wrongly.

Your patch is corrupted, but I've manually applied it.

I haven't marked it for stable because I worry a little that this will give
people unexpected changes in long term trends.  Better they see that only
on a major kernel version upgrade.

Applied to the fixes-togreg branch of iio.git.

Thanks,

Jonathan
