Hi Stafford,

Does this patch apply to your openrisc tree, but not to
linux-next?  I get a patch error when trying to apply it
to linux-next-20210805 and this warning is still present:

../arch/openrisc/kernel/setup.c:221:13: warning: no previous prototype for 'or32_early_setup' [-Wmissing-prototypes]
   221 | void __init or32_early_setup(void *fdt)
       |             ^~~~~~~~~~~~~~~~

presumably because some openrisc patches are not yet in linux-next??

thanks.
