In my case I triggered it intentionally. For one of our internal
project we want to strictly control the number of drivers/devices
allowed in kernel. To verify the feasibility of adding above support,
I intentionally failed few bus drivers and checked the behavior. In
one of those tests I hence came across the mentioned issue.

In any case, platform bus driver registration failure is a valid case
right ? Any issue we notice when this happens needs to be handled right?
