Song Hongyan 2edefc056e HID: intel-ish: ipc: handle PIMR before ish_wakeup also clear PISR busy_clear bit ... Host driver should handle interrupt mask register earlier than wake up ish FW else there will be conditions when FW interrupt comes, host PIMR register still not set ready, so move the interrupt mask setting before ish_wakeup. Clear PISR busy_clear bit in ish_irq_handler. If not clear, there will be conditions host driver received a busy_clear interrupt (before the busy_clear mask bit is ready), it will return IRQ_NONE after check_generated_interrupt, the interrupt will never be cleared, causing the DEVICE not sending following IRQ. Since PISR clear should not be called for the CHV device we do this change. After the change, both ISH2HOST interrupt and busy_clear interrupt will be considered as interrupt from ISH, busy_clear interrupt will return IRQ_HANDLED from IPC_IS_BUSY check.
