I wasn't sure how to handle this since it's been a problem since 3.10 
but no one has mentioned it (or patched it).

I assume this is because:
a) pinctrl is only used for I2C in mainline - and there is no mainline 
I2C consumer device drivers for the WonderMedia devices
b) most  users are using the non-mainline kernel which has more support 
(as nasty as some of it is).
