OK! The URL in commit message is ok to stay?

Yes, it's supported by drivers/iio/accel/bma180.c though I have to 
admit that this name is a bit misleading. (bosch-bma.c would 
better, I guess).

And I was a bit surprised that it worked out of the box too, but the 
device was present under /sys and I was able to read x, y, z and 
temperature values.
