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 Tristan Madani (2): 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() drivers/iio/imu/inv_mpu6050/inv_mpu_acpi.c | 7 +++++-- drivers/iio/light/cm32181.c | 5 +++-- 2 files changed, 8 insertions(+), 4 deletions(-) -- 2.47.3
