[PATCH 1/4] iio: accel: kxcjk-1013: Simplify ACPI ROTM mount matrix retreival

[Hans de Goede <hdegoede@redhat.com>]

There is no reason to limit the parsing of the ROTM mount matrix to only
ACPI devices with an ACPI HID (Hardware-ID) of "KIOX000A". If kxcjk-1013
ACPI devices with another HID have a ROTM method that should still be
parsed and if the method is not there then the:

	if (!adev || !acpi_has_method(adev->handle, "ROTM"))
		return false;

check will skip checking the ROTM method silently.

Move the check to see if there is an ACPI companion at all into
kxj_acpi_orientation() and drop the wrapper checking the HID.
