I was thinking of adding the platform_device.h (I liked your suggestion) 
in the include/kunit/

Probably so. Still, I am not the one who needs to deal with the 
conflicts. Hence I like at least asking if people see good way to avoid 
them in the first place.

Besides, I was not sure if you were planning to add similar helper or 
just wrappers to individual functions. Wanted to ping you just in case 
this has some impact to what you do.

This patch was should have contained the 
include/kunit/platform_device.h. That file was pulling the Kunit people 
in recipients but I messed up things with last minute changes so both 
the header and people were dropped. I'll fix this for v5.

Yours,
