Subject: [PATCH v3] iio: imu: lsm6dsx: Fix mount matrix retrieval
Date:   Fri, 14 Jul 2023 17:31:26 +0200

The function lsm6dsx_get_acpi_mount_matrix should return an error when ACPI
support is not enabled to allow executing iio_read_mount_matrix in the
probe function.

Fixes: dc3d25f22b88 ("iio: imu: lsm6dsx: Add ACPI mount matrix retrieval")
