[PATCH 6.1 007/122] drm/aperture: Remove primary argument

[PATCH 6.1 007/122] drm/aperture: Remove primary argument

[Greg Kroah-Hartman]

6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Daniel Vetter <daniel.vetter@ffwll.ch>

[ Upstream commit 62aeaeaa1b267c5149abee6b45967a5df3feed58 ]

Only really pci devices have a business setting this - it's for
figuring out whether the legacy vga stuff should be nuked too. And
with the preceding two patches those are all using the pci version of
this.

Which means for all other callers primary == false and we can remove
it now.

v2:
- Reorder to avoid compile fail (Thomas)
- Include gma500, which retained it's called to the non-pci version.

v4:
- fix Daniel's S-o-b address

v5:
- add back an S-o-b tag with Daniel's Intel address
