You are right. It compiles if I have CONFIG_INV_MPU6050_IIO built into
the kernel, which is what I'm using to boot the board, but fails when
compiled as a module. Good catch 0-day!

The patch won't apply to Linus's current master branch and I assumed
that iio/togreg didn't have the required changes as well. Sorry about
the noise.

I'll send a v2 before the weekend.
