[PATCH 0/3] radeon cursor patches

[Michel Dänzer]

While reviewing Nicholas Miell's patch 'drm/radeon/kms: fix cursor image
off-by-one error', I noticed at least one other bug (fixed by patch 2, and one
potential bug fixed by patch 3) and opportunities for cleanup.

Patch 1 is based on Nicholas' patch and can be dropped if he amends his patch
along the same lines.

[PATCH 1/3] drm/radeon: Simplify cursor x/yorigin calculation.
[PATCH 2/3] drm/radeon: Update AVIVO cursor coordinate origin before
[PATCH 3/3] drm/radeon: Set cursor x/y to 0 when x/yorigin > 0.
