commit512592779aupstream. Commita753bfcfdb("intel_th: Make the switch allocate its subdevices") factored out intel_th_subdevice_alloc() from intel_th_populate(), but got the error path wrong, resulting in two instances of a double put_device() on a freshly initialized, but not 'added' device. Fix this by only doing one put_device() in the 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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
