[ Upstream commit 0d28f49412405d87d3aae83da255070a46e67627 ] When performing a warm reset in ishtp bus driver, the ishtp_cl_device will not be removed, its fw_client still points to the already freed ishtp_device.fw_clients array. Later after driver finishing ishtp client enumeration, this dangling pointer may cause driver to bind the wrong ishtp_cl_device to the new client, causing wrong callback to be called for messages intended for the new client. This helps in development of firmware where frequent switching of firmwares is required without Linux reboot.

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.
