commit2ec1615017upstream. The current ordering of code in device_del() triggers a WARN_ON() in device_links_purge(), because of an unexpected link status. The device_links_unbind_consumers() call in device_release_driver() has to take place before device_links_purge() for the status of all links to be correct, so move the device_links_purge() call in device_del() after the invocation of bus_remove_device() which calls device_release_driver().

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.
