When the audio driver selects CONFIG_PXA_SSP to be a loadable module on a platform other than PXA, and the PXA SPI driver is built-in, we get a link error in the SPI driver:

While trying to write up a better changelog, I found that I had run into this before and attempted a different fix, see https://patchwork.kernel.org/patch/8879921/
The commit I referred to in "Fixes:" did not introduce a new problem at all, but it appears to have made it more likely to run into this situation.
Sending a third patch now, again different.
Mark, let me know if you want something else instead.
