drm/i915: move check of intel_crtc_cursor_set_obj() out
Move check inside intel_crtc_cursor_set_obj() to intel_check_cursor_plane(), we only use it there so move them out to make the merge of intel_crtc_cursor_set_obj() into intel_check_cursor_plane() easier. This is another step toward the atomic modesetting support and unification of plane operations such pin/unpin of fb objects on i915. v2: take Ville's comment: move crtc_{w,h} assignment a bit down in the code v3: take Ville's comment: kept only the restructuring changes, the rest of the code was moved to a separated patch since it is a bug fix (we weren't checking sizes when the fb was the same) Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> [danvet: Fixup commit message mixup.] Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
