The correct sequence for bridge initialization is: 1. devm_drm_bridge_alloc() 2. drm_bridge_add() 3. drm_bridge_attach() For bridges missing either 1 or 2 there are warnings in place already, presenting an explanatory error message. Bridges missing both 1 and 2 would still face a poorly understandable message, as reported in a recent regression report [0]: WARNING: [...] at [...]/lib/refcount.c:25 drm_bridge_attach+0x2c/0x1dc ... Call trace: ... drm_bridge_attach ... Add a new warning to ensure an understandable message is logged in such cases. Use the same message and warning message already in place in drm_bridge_add().

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 reStructuredText markup notation.
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.
