Linux kernel source tree

The ACPI "ROTM" rotation matrix parsing code atm is already duplicated between bmc150-accel-core.c and kxcjk-1013.c and a third user of this is coming. Add an iio_read_acpi_mount_matrix() helper function for this. The 2 existing copies of the code are identical, except that the kxcjk-1013.c has slightly better error logging. To new helper is a 1:1 copy of the kxcjk-1013.c version, the only change is the addition of a "char *acpi_method" parameter since some bmc150 dual-accel setups (360° hinges with 1 accel in kbd/base + 1 in display) declare both accels in a single ACPI device with 2 different method names for the 2 matrices. This new acpi_method parameter is not "const char *" because the pathname parameter to acpi_evaluate_object() is not const. The 2 existing copies of this function will be removed in further patches in this series. Acked-by: Rafael J.

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 reStructuredText 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.
