[PATCH] m68k: /proc/hardware depends on PROC_FS

[PATCH] m68k: /proc/hardware depends on PROC_FS

[Randy Dunlap]

When CONFIG_PROC_FS is not set, there is a build error for an unused
function. Make PROC_HARDWARE depend on PROC_FS to prevent this error.

In file included from ../arch/m68k/kernel/setup.c:3:
../arch/m68k/kernel/setup_mm.c:477:12: error: 'hardware_proc_show' defined but not used [-Werror=unused-function]
  477 | static int hardware_proc_show(struct seq_file *m, void *v)
      |            ^~~~~~~~~~~~~~~~~~

Fixes: 66d857b08b8c ("m68k: merge m68k and m68knommu arch directories") # v3.0

Thanks for your patch!

Reviewed-by: Geert Uytterhoeven <geert@linux-m68k.org>
i.e. will queue in the m68k for-v6.3 branch.

I'll move the "depends ..." line below the "bool ..." line while applying,
as that's where the dependencies are usually listed.

Agreed. I don't know how I did it like that.
