Hans de Goede 0a30353bec platform/x86: int3472: Check for adev == NULL 
[ Upstream commit cd2fd6eab4 ]

Not all devices have an ACPI companion fwnode, so adev might be NULL. This
can e.g. (theoretically) happen when a user manually binds one of
the int3472 drivers to another i2c/platform device through sysfs.

Add a check for adev not being set and return -ENODEV in that case to
avoid a possible NULL pointer deref in skl_int3472_get_acpi_buffer().

README 

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 reStructuredText 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.
