Subject: linux-next: build warning after merge of the tegra tree

---

Hi all,

After merging the tegra tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

In file included from drivers/soc/tegra/fuse/fuse-tegra.c:7:
include/linux/device.h:136:33: warning: 'dev_attr_production' defined but not used [-Wunused-variable]
136 | struct device_attribute dev_attr_##_name = __ATTR_RO(_name)
| ^~~~~~~~~
drivers/soc/tegra/fuse/fuse-tegra.c:441:8: note: in expansion of macro 'DEVICE_ATTR_RO'
441 | static DEVICE_ATTR_RO(production);
| ^~~~~~~~~~~~~~

Introduced by commit

2258fe488a20 ("soc/tegra: fuse: Expose Tegra production status")
