On some devices the INT33D6 vbtn device is only used to report tablet-mode / docked status (switches) and there are no vbtn managed buttons. On these devices there is no VBDL object. Move the VBDL check to a intel_vbtn_has_buttons() helper and only exit from intel_vbtn_probe() with -ENODEV when there are both no buttons and no switches. Also only report the buttons being present to userspace if the has_buttons check has succeeded.

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.
