Planes without an alpha property, using __drm_atomic_helper_plane_reset will have their plane state alpha initialised as zero, which represents a transparent alpha. If this value is then used for the plane, it may not be visible by default, and thus doesn't represent a good initialisation state. Update the default state->alpha value to DRM_BLEND_ALPHA_OPAQUE unconditionally when the plane is reset.

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.
