There is now a way to ensure all platform devices get a unique name when populated from the device tree, and the DCR_NATIVE code path is broken anyway. PowerPC Cell (PS3) is the only platform that actually uses this path. Most likely nobody will notice if it is killed. Remove the code and associated ugly #ifdef. The user-visible impact of this patch is that any DCR device on Cell will get a new name in the /sys/devices hierarchy.
