When you're saying about "both" patches, you're referring to the
original one plus this fix, right?

I know why I missed... I was not c/c at the original patch. Well,
I received it at my LKML inbox, but nobody reads all LKML emails
those days.

Sure I will look on it in a few. I'm not rushing with that 7
patch series, as the most important thing for my workflow is to build
all media drivers on i386/x86_64. Building on other archs is just a
plus, as I intend some day to also incrementally do test building on arm
as I receive/merge patches, but I don't do it yet.

Thanks,
