Subject: iio: imu: lsm6dsx: Fix mount matrix retrieval
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6811694eb2f6b7a4e97be2029edc7dd6a39460f8;p=linux.git

iio: imu: lsm6dsx: Fix mount matrix retrieval

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.
