When request firmware fails, brcmf_ops_sdio_remove is being called and brcmf_bus freed. In such circumstancies if you do a suspend/resume cycle the kernel hangs on resume due a NULL pointer dereference in resume function. So in brcmf_sdio_firmware_callback() we need to unbind the driver from both sdio_func devices when firmware load failure is indicated.

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.
