Instead check for master status, in case we've raced. This is the last exception to the general rule that we restore fbcon only when there's no master active. Compositors are supposed to drop their master status before they switch to a different console back to text mode (or just switch to text mode directly, without a vt switch). This is known to break some subtests of kms_fbcon_fbt in igt, but they're just wrong - it does a graphics/text mode switch for the vt without updating the master status. Also add a comment to the drm_client->restore hook that this is expected going forward from all clients (there's currently just one). v2: Also drop the force in pan_display v3: Restore the _force to pan_display, this actually means _locked in that path.

README
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.
