Currently autoloading for SPI devices does not use the DT ID table, it uses
SPI modalises. Supporting OF modalises is going to be difficult if not
impractical, an attempt was made but has been reverted, so this series
adds SPI IDs where they aren't provided for a given modalias.

WM1814, WM8997 and WM8998 do not have a SPI interface, which is why they
aren't in the table of SPI IDs.

They're listed as valid DT compatibles for SPI so will now generate
warnings on boot, the driver should not list those compatibles if
they're not valid.

Yeah we should really be having different lists for SPI and I2C
here I guess. I am happy to have a quick look at doing a patch
for that, unless you particularly want to fix it up?
Thanks,

Just this one, or should I drop the set?
