With CONFIG_ACPI=n and -Werror, 0-day reports: drivers/iio/humidity/am2315.c:259:36: error: 'am2315_acpi_id' defined but not used According to Andy Shevchenko, the ACPI ID used in this driver is fake and does not really exist. Remove it and with it ACPI support from the driver. Note that, if an explicit of_device_id table is added to the driver it could support the PRP0001 based ACPI approach.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
