mainlining shenanigans
We're currently failing to reset everything in display_info.hdmi which will potentially cause us to use stale information when swapping monitors. Eg. if the user replaces a HDMI 2.0 monitor with a HDMI 1.x monitor we will continue to think that the monitor supports scrambling. That will lead to a black screen since the HDMI 1.x monitor won't understand the scrambled signal. Fix the problem by clearing display_info.hdmi fully. And while at eliminate some duplicated code by calling drm_reset_display_info() in drm_add_display_info().

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ 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.
