VKMS currently supports only one CRTC, so it make no sense to have this index configurable. To avoid issues, replace this hardcoded index by drm_crtc_mask when applicable. There is no need to manually set a crtc mask on primary and cursor plane as it is automatically set by drmm_crtc_alloc_with_planes. In addition, this will remove the use of an uninitialized structure in vkms_add_overlay_plane. This currently works by chance because two things: - vkms_plane_init always set a possible_crtcs value, so the problematic branch is never used; - drm_crtc_mask on an kzalloc'd drm_crtc returns BIT(0), and the VKMS CRTC always have this id.

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.
