[ Upstream commit a8627176b0 ]
In the error handling code of iwl_req_fw_callback(), iwl_dealloc_ucode()
is called to free data. In iwl_drv_stop(), iwl_dealloc_ucode() is called
again, which can cause double-free problems.
To fix this bug, the call to iwl_dealloc_ucode() in
iwl_req_fw_callback() is deleted.
This bug is found by a runtime fuzzing tool named FIZZER written by us.

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.
