To support multiple template digests, the static array entry->digest has been replaced with a dynamically allocated array in commitaa724fe18a("ima: Switch to dynamically allocated buffer for template digests"). The array is allocated in ima_alloc_init_template() and if the returned pointer is NULL, ima_free_template_entry() is called. However, (*entry)->template_desc is not yet initialized while it is used by ima_free_template_entry(). This patch fixes the issue by directly freeing *entry without calling ima_free_template_entry().

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.
