In commit003342a500("drm/i915: Keep track of active forcewake domains in a bitmask") I forgot to adjust the newly introduce fw_domains_active state across reset. This caused the assert_forcewakes_inactive to trigger during suspend and resume if there were user held forcewakes. v2: Bitmask checks are required since vfuncs are not always present. v3: Move bitmask tracking to get/put vfunc for simplicity.

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.
