Notice that acpi_ec_add() calls acpi_config_boot_ec() when it finds that the device object passed to it represents a "boot" EC, but in that case the ec pointer passed to acpi_config_boot_ec() is guaranteed to be equal to boot_ec and ec->handle is passed as the handle argument to it, so acpi_config_boot_ec() really only calls acpi_ec_setup() and prints a message. Avoid the pointless checks in acpi_config_boot_ec() by calling acpi_ec_setup() directly and print the message separately. With the above changes in place, there are no users of acpi_config_boot_ec(), so drop it. No intentional functional impact except for a changed message. Signed-off-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.
