You miss quite a few of them (atmel, nandsim, sunxi_nand at least,
there might be others).

And here as well some of the drivers are still printing error messages
after mem allocation failures (amd76xrom, ck804xrom, esb2rom, ichxrom,
vmu-flash).

I didn't check but I'm pretty sure you missed some of them here too.
