The second switch-case has no real purpose: - for I8K_BIOS_VERSION, val does not represent a return value, making the check for error values unnecessary. - for I8K_MACHINE_ID, val remains zero, so the error check is unnecessary too. Remove the switch-case and move the calls to copy_to_user() into the first switch-case for I8K_BIOS_VERSION/_MACHINE_ID. Omit buff[] since data->bios_machineid already contains the string with the necessary zero padding through devm_kzalloc(). Tested on a Dell Inspiron 3505.

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.
