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.

If you have one of Odroid boards with Exynos, then you can nicely test
Exynos. Others - depends, on board.
Anyway I can test them for you. I just want to be sure that Greg waits
for this testing.

Worse case, QEMU has some Exynos4210 emulation that is usable.

Thanks,

M.
