Greg, Arnd,
gentle ping for this. I noticed that some maintainers are complaining
about being spammed with patches converting old drivers to using
devm_platform_ioremap_resource() and there's even a patch removing the
relevant coccinelle script on the list, but I think for new drivers
these are still useful. Do you want to pick them up for v5.5 (or at
all)?
Bart
