MTD already allocates backing_dev_info dynamically. Convert it to use generic infrastructure for this including proper refcounting. We drop mtd->backing_dev_info as its only use was to pass mtd_bdi pointer from one file into another and if we wanted to keep that in a clean way, we'd have to make mtd hold and drop bdi reference as needed which seems pointless for passing one global pointer...

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.
