firmware_loading_complete is used to synchronize operations on rproc while asynchronous firmware loading is in progress. However, rproc_boot() no longer waits on firmware_loading_complete. Hence drop this completion variable altogether and handle the race between rproc_del() and rproc_boot() using new state RPROC_DELETED. The request_firmware_nowait() will hold the reference to rproc device by using a get_device()/put_device(), so the rproc struct will remain valid even when we return from rproc_del() before the asynchronous call to rproc_fw_config_virtio() completes.

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.
