This keycode is used by Dell as a no-op for keys that should have
no function.
This keycode is never triggered by a keypress in practice, rather
it is included from the 0xB2 DMI table at startup.
This prevents the following messages from being logged at startup on a
Dell Inspiron 5593:
dell_wmi: firmware scancode 0x48 maps to unrecognized keycode 0xffff
dell_wmi: firmware scancode 0x50 maps to unrecognized keycode 0xffff
as per this code comment:
Log if we find an entry in the DMI table that we don't
understand. If this happens, we should figure out what
the entry means and add it to bios_to_linux_keycode.

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.
