Solves http://bugzilla.kernel.org/show_bug.cgi?id=11127 The old rtc.c driver did it and some drivers (like rtc-sh) do it in their release function, though they should not -- because they should provide the irq_set_state op and the rtc framework itself should care about it. This patch makes it do so. I am aware that some drivers, like rtc-sh, handle userspace PIE sets in their ioctl op (instead of having the framework call the op), exporting the irq_set_state op at the same time. The logic in rtc_irq_set_state should make sure it doesn't matter and the driver should not need to care stopping periodic interrupts in its release routine any more. The correct way, in my opinion, should be this: 1) The driver provides the irq_set_state op and does not care closing the interrupts in its release op. 2) If the driver does not provide the op and handles PIE in the ioctl op, it's reponsible for closing them in its release op. 3) Something similar for other IRQs, like UIE -- if there's no in-kernel API like irq_set_state, handle it in ioctl and release ops. The framework will be responsible either for everything or for nothing. (This will probably change later.)
