All DRM bridges are now supposed to be allocated using devm_drm_bridge_alloc(), which is cleaner and necessary to support refcounting. In the absence of a drm_bridge_init() or such initialization function, document the new mandatory alloc function on the first DRM bridge core function that is called after allocation, i.e. 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.
