drivers/rtc/rtc-da9052.c was converted to use
devm_request_threaded_irq() after linux-3.8, so I cannot apply this
patch to mainline. Can you please prepare a patch against 3.9-rc3?
Do you believe that the patch should be backported into -stable
kernels? If so, Greg will need a different version of it - ie, the one
you have just sent. Please send that to him at the appropriate time
(say, when you see me drop the 3.9-rc3 version from the -mm tree).
