Currently, if we try to unbind the platform device, the remove will succeed, but the removal won't undo most of the registration, leaving partially-configured PCI devices in the system. This allows, for example, a simple 'lspci' to crash the system, as it will try to touch the freed (via devm_*) driver structures, e.g., on RK3399: # echo f8000000.pcie > /sys/bus/platform/drivers/rockchip-pcie/unbind # lspci So let's implement device remove().

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.
