Hello Andy,
thanks for the patch. I cannot test since I don't have an ACPI system with our sensor, but it looks coherent.

Subject: [PATCH v1 03/13] iio: imu: inv_mpu6050: Replace strange way of checking type of enumeration
This Message Is From an External Sender
This message came from outside your organization.
When device is enumerated via ACPI the respective device node is of
ACPI device type. Use that to check for ACPI enumeration, rather than
calling for full match which is O(n) vs. O(1) for the regular check.
