I have the same question on the utility of this. A memory allocation
error so early on is not going to result in a bootable system anyway.
So, I wonder if its better to just BUG() in such cases. That will
actually help faster debug than returning an error back. I know the push
back on using BUG(), but clock drivers are special, and I think thats
why its seems to be used quite a bit already.

Thanks,
Sekhar
