From: Thierry Reding <treding@xxxxxxxxxx>
Currently drivers that set the DRIVER_MODESET feature are considered to
be non-legacy drivers. At the same time DRIVER_MODESET implies that the
mode-setting IOCTLs are available. It is therefore not possible to
distinguish between a non-legacy driver with full mode-setting support
and a non-legacy driver without mode-setting functionality.
To separate the meaning of "legacy" and "modeset", a new driver feature
is introduced: DRIVER_LEGACY. The meaning of DRIVER_MODESET can then be
changed to apply to the mode-setting functionality only, irrespective
of whether it is legacy or not.
Mark all legacy drivers appropriately.
