If I'm understanding [1] properly, both spelling variants are correct.

I was reluctant to Cc stable because I'm not sure which versions need
to be fixed, as I've seen an earlier version (3.0 something or a bit
before that probably) working without this (no idea why); also I'm not
sure about that msleep as it's deduced solely from experimenting with
a particular i.MX model, I hoped someone from Freescale would comment
on it. I've seen your review [2] on a related patch and my fix should
have been obvious to Suresh (and trivial to test on different boards),
yet he didn't implement it, that worries me a bit.
