[PATCH] iio: accel: bmc150: Accept any trigger

[Linus Walleij <linus.walleij@linaro.org>]

The BMC150 driver checks to see that the trigger it is
using is one of its own.

Not nice for my system where the IRQ line from the BMA222
is not connected so there is *no* trigger I can use.

This seems just plain wrong to me. Certainly a userspace
process will want to use the trigger from one single sensor
even of it is reading say three different sensors for some
sensor fusion.

Delete this trigger check.
