Arend Van Spriel 7a51461fc2 brcmfmac: unbind all devices upon failure in firmware callback
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.
