Sorry, this was a commit message mistake. The code is correct and so is 
the patch: just the NULL check is correct for the previous variant and 
IS_ERR is correct for devm_ioremap_resource. I confused myself while 
writing the commit message after the fact.

I unfortunately don't have any Exynos devices where I could test the 
code (I have a couple but no serial connections, and I have no idea if 
mailine would run on them). I'll mark v3 as RFT.
