So how many existing userspace applications does this patch break? Has this system been widely deployed so a kernel upgrade will cause problems for people?
But applied anyway, unless someone screams about it real soon now. That seems to be the only way to get people to tell us about their use cases.
Could you consider adding names to the exported GPIO pins on the vt8500 series please? Then userspace can atleast try to locate the right pin.
Yours, Linus Walleij
