Subject: [PATCH] drm/radeon: Always store CRTC relative
radeon_crtc->cursor_x/y values
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

We were storing viewport relative coordinates for AVIVO/DCE display engines. However, radeon_crtc_cursor_set2 and radeon_cursor_reset pass radeon_crtc->cursor_x/y as the x/y parameters of radeon_cursor_move_locked, which would break if the CRTC isn't located at (0, 0).
