The device_attribute .show() and .store() methods gained an extra
parameter in v2.6.13, but the example in the documentation for the
7-segment header file was never updated. Add the missing parameters.
While at it, get rid of the (misspelled) deprecated symbolic
permissions, and switch to DEVICE_ATTR_RW(), which was introduced in
v3.11

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.
