The extcon files explains the detailed operation for functions and
what is meaning of extcon structure. There are different explanation
even if the same argument.

So, it modifies the description for both functions and structures
in order to improve the readability and guide the role of functions
more well.

Also, this patch fixes the mismatching license info as a GPL v2
and removes the inactive author information.

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

This is the driver for the USB Type C cable detection mechanism
built into the ChromeOS Embedded Controller on systems that
have USB Type-C ports.

At present, this allows for the presence of display out, but in
future, it may also be used to notify host and device type cables
and the presence of power.

acpi_device_id are not supposed to change at runtime. All functions
working with acpi_device_id provided by <acpi/acpi_bus.h> work with
const acpi_device_id. So mark the non-const structs as const.
