[PATCH v2] iio: imu: inv_mpu6050: Select I2C_MUX again

[PATCH v2] iio: imu: inv_mpu6050: Select I2C_MUX again

[Linus Walleij]

commit f7072198f217 ("iio: imu: Fix inv_mpu6050 dependencies")
undid the explicit selection of I2C_MUX previously
done by the driver, because I2C_MUX implicitly depended
on HAS_IOMEM.

However commit 93d710a65ef0 ("i2c: mux: fix up dependencies")
cleared up the situation properly and drivers that need
to select I2C_MUX can now do so again.

It makes a lot of sense for a driver to select the driver
infrastructure it needs so restore the natural order of
things.

Applied to the togreg branch of iio.git and pushed out as testing
to let the autobuilders have a good poke at it.

Thanks,
