With the preceding patches it's become defunct. Also I'm about to add a different boolean argument, so it's better to keep the confusion down to the absolute minimum. v2: Since the hypervfb patch got droppped (it's only a pci device for gen1 vm, not for gen2) there is one leftover user in an actual driver left to touch. v4: - fixes to commit message - fix Daniel's S-o-b address v5: - add back an S-o-b tag with Daniel's Intel address Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Javier Martinez Canillas <javierm@redhat.com> Cc: Helge Deller <deller@gmx.de> Cc: linux-fbdev@vger.kernel.org Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: "K.
