If we fail to reinit the FW when resetting the device (in the synchronous version of mwifiex_init_hw_fw() -> mwifiex_fw_dpc()), mwifiex_fw_dpc() will tear down the interface and free up the adapter. But we don't actually check for all failure cases of mwifiex_fw_dpc(), so some of them fall through and dereference adapter->fw_done with a freed adapter, causing a use-after-free bug. In any case, mwifiex_fw_dpc() will always signal FW completion -- in the error OR success case -- so at best, this was repeat work. Let's not do it.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
