When kobject_init_and_add() returns an error, it should be handled
because kobject_init_and_add() takes a reference even when it fails. If
this function returns an error, kobject_put() must be called to properly
clean up the memory associated with the object.
Therefore, replace calling kfree() and call kobject_put() and add a
missing kobject_put() in the edac_device_register_sysfs_main_kobj()
error path.

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.
