This reverts commit0c08754b59. commit0c08754b59("drm/panel: Add device_link from panel device to DRM device") creates a circular dependency under these circumstances: 1. The panel depends on dsi-host because it is MIPI-DSI child device. 2. dsi-host depends on the drm parent device (connector->dev->dev) this should be allowed. 3. drm parent dev (connector->dev->dev) depends on the panel after this patch. This makes the dependency circular and while it appears it does not affect any in-tree drivers (they do not seem to have dsi hosts depending on the same parent device) this does not seem right. As noted in a response from Andrzej Hajda, the intent is likely to make the panel dependent on the DRM device (connector->dev) not its parent. But we have no way of doing that since the DRM device doesn't contain any struct device on its own (arguably it should). Revert this until a proper approach is figured out.

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.
