I think both Maxime's change (polling a new HW bit) and Robert J's
change (move to a threaded IRQ) are good. I'll take another look, but I
expect I'll take Maxime's v4 for the 4.0 cycle, and Robert J's v2 for
4.1 (or will we just jump straight to 5.0? I never know). Will I see a
patch to convert to msleep() and/or a jiffies timeout in the near
future?
