[Letux-kernel] two accelerometers + iio_bridge considered harmful

Hi,

I found out something strange.
At least in my gta04a5, there are two accelerometers:
the bmc150 and the bno055.

Disabling the bmc150-accel-i2c.ko module
makes the input bridge work reliably, enabling it again, lets it crash
again.

Are both populated on every gta04a5?

And then there is another bug:
rmmod bno055

makes the bridge disappear 
modprobe bno055

does not bring it back

Regards,
Andreas
