[Consult] About only one Signed-of-by for the patches

[Chen Gang <gang.chen.5i5j@gmail.com>]

Hello Maintainers:

I find some of patches are only Signed-of-by me, are they OK?

e.g:

commit d7de15786d1a10fa18b80fd44026d442e7a84bd2

    arch:unicore32:mm: add devmem_is_allowed() to support STRICT_DEVMEM
    
    unicore32 supports STRICT_DEVMEM, so it needs devmem_is_allowed(), like
    some of other architectures have done (e.g. arm, powerpc, x86 ...).
    
    The related error with allmodconfig:
    
        CC      drivers/char/mem.o
      drivers/char/mem.c: In function â<U+0080><U+0098>range_is_allowedâ<U+0080><U+0099>:
      drivers/char/mem.c:69: error: implicit declaration of function â<U+0080><U+0098>devmem_is_allowedâ<U+0080><U+0099>

      make[1]: *** [drivers/char] Error 2
