[ Upstream commite6d773f93a] Afer commit1fa5ae857b("driver core: get rid of struct device's bus_id string array"), the name of device is allocated dynamically, it needs be freed when device_register() returns error. As comment of device_register() says, one should use put_device() to give up the reference in the error path. Fix this by calling put_device(), then the name can be freed in kobject_cleanup(), and sdbg_host is freed in sdebug_release_adapter(). When the device release is not set, it means the device is not initialized. We can not call put_device() in this case. Use kfree() to free memory.

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.
