Subject: [PATCH v2] iio: imu/mpu6050: support dual-edge IRQ
CAUTION: This email originated from outside of the organization. Please make sure the sender is who they say they are and do not click links or open attachments unless you recognize the sender and know the content is safe.
Make mpu6050 usable on platforms which provide only any-edge interrupts.
This also covers shared interrupt case.

v2:
just remove the dev_warn() message
