Thadeu Lima de Souza Cascardo ee0b0d7baa wifi: rtlwifi: fix memory leaks and invalid access at probe error path
[ Upstream commit e7ceefbfd8d447abc8aca8ab993a942803522c06 ]

Deinitialize at reverse order when probe fails.

When init_sw_vars fails, rtl_deinit_core should not be called, specially
now that it destroys the rtl_wq workqueue.

And call rtl_pci_deinit and deinit_sw_vars, otherwise, memory will be
leaked.

Remove pci_set_drvdata call as it will already be cleaned up by the core
driver code and could lead to memory leaks too. cf. commit 8d450935ae
("wireless: rtlwifi: remove unnecessary pci_set_drvdata()") and
commit 3d86b93064 ("rtlwifi: Fix PCI probe error path orphaned 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.
