[ Upstream commit78570f8873] The hwmon pointer wont be NULL if the registration fails. Though the exit code path will assign it to ctrl->hwmon_device. Later nvme_hwmon_exit() will try to free the invalid pointer. Avoid this by returning the error code from hwmon_device_register_with_info().

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.
