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.

Commit 669c9215 ("drm/atomic: Make async plane update checks work as intended, v2.") assumed incorrectly that if only 1 plane is matched in the loop, the variables will be set to that plane. In reality we reset them to NULL every time a new plane was iterated. This behavior is surprising, so fix this by making the for loops only assign the variables on a match. When we have not added all the planes/crtc/connector to the state, and there's a few NULL ones after the last one we iterated, te assumption is broken that the pointers will hold the values from the last loop iteration, which holds true for all other for_each macros we're using. Except of course the iterator pointer itself, but that one really is entirely internal.
