IMO, flipping the dependency looks saner to me.  The SPI function call
is a kind of add-on, after all.

Yes, that's definitely the intention of the code.

I just ran into the same problem again on randconfig testing, after
the bug had been
gone before my vacation:

    sound/soc/codecs/rt5514.o: In function `rt5514_dsp_voice_wake_up_put':
    rt5514.c:(.text+0x2068): undefined reference to `rt5514_spi_burst_write'
    rt5514.c:(.text+0x20c8): undefined reference to `rt5514_spi_burst_write'

Is anyone looking into this? My original patch
(https://patchwork.kernel.org/patch/9871255/) still fixes it but needs a
minor change to apply now. When I last looked into changing
the dependency in the code, I couldn't quite figure out how to
do it there.
