Notice that the return value of acpi_ec_init() is discarded anyway, so it can be void and it doesn't need to check the return values of acpi_bus_register_driver() and acpi_ec_ecdt_start() called by it. Thus the latter can be void too and it really has nothing to do if acpi_ec_add() has already found an EC matching the boot one in the namespace. Also, acpi_ec_ecdt_get_handle() can be folded into it. Modify the code accordingly and while at it create a propoer kerneldoc comment to document acpi_ec_ecdt_start() and move the remark regarding ASUS X550ZE along with the related bug URL from acpi_ec_init() into that comment. Additionally, fix up a stale comment in acpi_ec_init(). Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
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.
