[PATCH v1 1/1] iio: accel: mma7660: Drop wrong use of ACPI_PTR()

From: Andy Shevchenko
Date: Thu Jun 16 2022 - 10:25:00 EST


ACPI_PTR() is more harmful than helpful. For example, in this case
if CONFIG_ACPI=n, the ID table left unused which is not what we want.

Instead of making linker to drop a section, drop ACPI_PTR().

As a side effect this makes driver ACPI and OF clean.
