[ Upstream commit8700af2cc1] Callback function rtrs_clt_dev_release() for put_device() calls kfree(clt) to free memory. We shouldn't call kfree(clt) again, and we can't use the clt after kfree too. Replace device_register() with device_initialize() and device_add() so that dev_set_name can() be used appropriately. Move mutex_destroy() to the release function so it can be called in the alloc_clt err 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.
