Since commit aed65af1cc ("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move the
power_supply_dev_type variable to be a constant structure as well, placing
it into read-only memory which can not be modified at runtime.
In order to accomplish that, export power_supply_attr_group in
power_supply.h and use it with the macro __ATTRIBUTE_GROUPS when defining
power_supply_dev_type in power_supply_core.c. Therefore the attribute group
is no longer static. Lastly, because power_supply_attr_groups is no longer
dynamically associated to power_supply_dev_type in
power_supply_init_attrs(), make the function receive zero arguments.

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.
