acpi_evaluate_object() will already return in error if the method does not exist. Checking if the method is absent before the acpi_evaluate_object() call is not needed. Remove acpi_has_method() calls to avoid additional work. Signed-off-by: Kelsey Skunberg <skunberg.kelsey@gmail.com> Reviewed-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 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.
