Linux kernel source tree
54087768db
We want DRM planes to be initialized in the following order: - primary planes - overlay planes - cursor planes to support existing userspace expectations for plane z-ordering. This means that we also need to register CRTCs after all planes have been initialized since overlay planes can be placed on any CRTC. So the only reason why we have the mode_info->planes list is to remember the primary planes for use later when we need to register the CRTC. Overlay planes have no purpose being in this list. DRM will cleanup any planes that we've registered for us, so the only planes that need to be explicitly cleaned up are the ones that have failed to register. By dropping the explicit free on every plane in the mode_info->planes list this patch also fixes a double-free in the case where we fail to initialize only some of the planes.

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.
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.
