From: Anirban Chakraborty <anirban.chakraborty@xxxxxxxxxx> The interrupt handler clears the interrupt status register for response updates in the base queue while working in the multique mode. This could lead to missing interrupt for async events, mail box completions etc. as these are also handled in the base queue. The fix ensures that the interrupt bit is not cleared for response updates in the ISR when the driver is working in multiqueue mode.
