[PATCH v2 0/2] iio: validate ACPI object types before package access

[Tristan Madani]

From: Tristan Madani <tristan@xxxxxxxxxxxxxxxxxxx>

Two IIO drivers access ACPI package members without validating the
returned object type.  Use acpi_evaluate_object_typed() to request
ACPI_TYPE_PACKAGE at evaluation time, and replace kfree() with
ACPI_FREE() for ACPI-allocated buffers.

Changes in v2:
- Use acpi_evaluate_object_typed() instead of manual post-eval type
  check, as suggested by Jonathan Cameron
- Replace kfree() with ACPI_FREE() for ACPI-allocated buffers

  iio: light: cm32181: validate ACPI object type in
    cm32181_acpi_get_cpm()
  iio: imu: inv_mpu6050: validate ACPI object types in
    asus_acpi_get_sensor_info()
