Runyu Xiao fa2e77ac5b m68k: dmasound: Keep the Q40 IRQ handler registered ... Q40PlayNextFrame() re-registers the sample IRQ after stopping it. This function can be called with dmasound.lock held and from the sample IRQ handler, so free_irq() and request_irq() can sleep or deadlock. A failed re-registration can also leave playback without an IRQ. Register one handler for the lifetime of the driver and select mono or stereo sample handling inside that handler. Call the frame completion path after releasing dmasound.lock so it can refill the queue safely.
