[ Upstream commit57a1681095] The function tpci200_register called by tpci200_install and tpci200_unregister called by tpci200_uninstall are in pair. However, tpci200_unregister has some cleanup operations not in the tpci200_register. So the error handling code of tpci200_pci_probe has many different double free issues. Fix this problem by moving those cleanup operations out of tpci200_unregister, into tpci200_pci_remove and reverting the previous commit9272e5d002("ipack/carriers/tpci200: Fix a double free in tpci200_pci_probe").

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.
