d2168146c2
A number of board files in arch/arm and arch/unicore32 explicitly reference platform_bus device as a parent for new platform devices. This is unnecessary, as platform device API guarantees that devices with NULL parent are going to by adopted by the mentioned "root" device. This patch removes or replaces with NULL such references.
