Fixes native drm clients like Fedora 23 Wayland which now appears to be able to use cursor hotspots without strange cursor offsets. Also fixes a couple of ignored error paths. Since the core drm cursor hotspot is incompatible with the legacy vmwgfx hotspot (the core drm hotspot is reset when the drm_mode_cursor ioctl is used), we need to keep track of both and add them when the device hotspot is set. We assume that either is always zero. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Sinclair Yeh <syeh@vmware.com>
