The fix is already posted via 
https://lore.kernel.org/patchwork/patch/1031226/.

Mark, Can you pick this up. We will still have to consider intel platform

where there is no soc_component associated with platform_name.

Other solution is to revert this patch and use client specific defer 
probe as

done in v1.
