[PATCH 2/3] iio: imu: mpu6050: Move request IRQ outside of probe trigger

[Daniel Baluta <daniel.baluta@intel.com>]

Besides signalling data ready, IRQ line of Invensense MPU
can also signal the status of slaves attached on secondary
I2C bus.

In order to prepare supporting secondary I2C interface we need
to detach IRQ request from data ready trigger creation.
