[PATCH] drm/nouveau: fix compile errors

[Rob Clark]

From: Rob Clark <rclark at redhat.com>

Perhaps some newer versions of gcc are more clever about this.

drivers/gpu/drm/nouveau/nvkm/subdev/top/gk104.c: In function 'gk104_top_oneinit':
include/linux/device.h:1164:45: error: 'inst' may be used uninitialized in this function [-Werror=maybe-uninitialized]
 #define dev_info(dev, fmt, arg...) _dev_info(dev, fmt, ##arg)
                                             ^
drivers/gpu/drm/nouveau/nvkm/subdev/top/gk104.c:32:18: note: 'inst' was declared here
  u32 data, type, inst;
                  ^
