[Dan Carpenter]

Hello Ben Skeggs,

The patch a9c44a88ca2f: "drm/nouveau/disp/nv50-: add channel
interfaces to control error interrupts" from May 8, 2018, leads to
the following static checker warning:

	drivers/gpu/drm/nouveau/nvkm/engine/disp/changf119.c:55 gf119_disp_chan_intr()
	warn: should '1 << chan->chid.user' be a 64 bit type?

drivers/gpu/drm/nouveau/nvkm/engine/disp/changf119.c
    51  void
    52  gf119_disp_chan_intr(struct nv50_disp_chan *chan, bool en)
    53  {
    54          struct nvkm_device *device = chan->disp->base.engine.subdev.device;
    55          const u64 mask = 0x00000001 << chan->chid.user;
                                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    56          if (!en) {
    57                  nvkm_mask(device, 0x610090, mask, 0x00000000);
    58                  nvkm_mask(device, 0x6100a0, mask, 0x00000000);
    59          } else {
    60                  nvkm_mask(device, 0x6100a0, mask, mask);
    61          }
    62  }
