[ Upstream commit27d2a2fd84] bigben_worker() checks report_field to be non-NULL. The check has been added in commit918aa1ef10("HID: bigbenff: prevent null pointer dereference") to prevent a NULL pointer crash. However, the true root cause was a missing check for output reports, patched in commitc7bf714f87("HID: check empty report_list in bigben_probe()"), where the type-confused report list_entry was overlapping with a NULL pointer, which was then causing the crash.

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.
