Aleksandr Mishin dc2694e474 platform/x86: dell-smbios: Fix error path in dell_smbios_init() [ Upstream commit `ffc17e1479` ] In case of error in build_tokens_sysfs(), all the memory that has been allocated is freed at end of this function. But then free_group() is called which performs memory deallocation again. Also, instead of free_group() call, there should be exit_dell_smbios_smm() and exit_dell_smbios_wmi() calls, since there is initialization, but there is no release of resources in case of an error. Fix these issues by replacing free_group() call with exit_dell_smbios_wmi() and exit_dell_smbios_smm(). Found by Linux Verification Center (linuxtesting.org) with SVACE.

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.
