It fixes a problem on our platform (QDF2432). Without this patch, we can't
use the PL011 at all.

Did it ever work before? Or is this new functionality?

No, it never worked before, so it's not a regression. I guess it all depends on how you define "fix". The driver loads and attempts to use the hardware, but it fails without this patch. The system locks up completely (I guess it throws an unhandled exception or something).

I guess if you take a very limited definition of "fix", then this isn't a fix. I can understand if you didn't want to take it for 4.6-rc7 or something, but for 4.6-rc2, I don't think it's inappropriate.

That's my two cents. We'd like to see it in 4.6-rc2, but the decision is yours.
