There are two callers of acpi_get_device_data(), acpi_bus_get_device() and acpi_bus_get_acpi_device(), but only one of them takes the int return value into account. Moreover, the latter knows that it passes a valid return pointer to acpi_get_device_data() and it properly clears that pointer upfront, so it doesn't need acpi_get_device_data() to do that. For this reason, rearrange acpi_get_device_data() to return a strct acpi_device pointer instead of an int and adapt its callers to that. While at it, rename acpi_get_device_data() to handle_to_device(), because the old name does not really reflect the functionality provided by that function. No intentional functional impact.

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.
