sysfs_emit() is preferred over sprintf() when formatting the value to be
returned to user space in show() functions, because it knows about sysfs
buffer specifics and has sanity checks.

Now that the SPDX tag is in all kobject files, that identifies the
license in a specific and legally-defined manner. So the extra GPL text
wording can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text. And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.
No copyright headers or other non-license-description text was removed.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
Update the kobject files files with the correct SPDX license identifier
based on the license text in the file itself. The SPDX identifier is a
legally binding shorthand, which can be used instead of the full boiler
plate text.
This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

Rusty pointed out that the module license should be "GPL v2" to properly
match the notice at the top of the files, so make that change.

Use kstrtoint function instead of sscanf and check for return values.

In line with practice for module parameters, we're adding a build-time
check that sysfs files aren't world-writable.

None of these (init|exit) functions is called from other functions which
is outside the kernel module mechanism or kernel itself, so mark them as
{static|__init|__exit}.

This is a simple kobject module, showing how to use kobj_attributes in
basic and more complex ways.
