Closing as obsolete, if this is incorrect please update the bug having tested
versus a recent kernel

[PATCH RESEND] drm: fix case where panic notifier isn't unregistered

The framebuffer helper panic notifier is unregistered, in drm_fb_helper_fini(), when
kernel_fb_helper_list goes from being non-empty to empty. However, in
drm_fb_helper_single_fb_probe(), it's possible for the panic notifier to be registered without an
element being added to this list if a driver's probe function returns 0. Make sure that an attempt to add the
panic notifier is made only when adding an element to kernel_fb_helper_list.

This should hopefully have none of the whitespace damage introduced by my email client last time.

Then, the proper course of action would be to add to the linux API, sized
atomic operation first, wouldn't it?

[PATCH 01/10] drm/radeon: remove radeon_fence_create

It is completely unnecessary to create fences
before they are emitted, so remove it and a bunch
of checks if fences are emitted or not.

[PATCH] drm/edid/quirks: ViewSonic VA2026w

Entirely new class of fail for this one.  The detailed timings are for
normal CVT but the monitor really wanted CVT-R.

[PATCH] drm/radeon: fix XFX quirk

From: Alex Deucher <alexander.deucher <at> amd.com>

Only override the ddc bus if the connector doesn't have
a valid one.  The existing code overrode the ddc bus for
all connectors even if it had ddc bus.

Fixes ddc on another XFX card with the same pci ids that
was broken by the quirk overwriting the correct ddc bus.
