Sudeep Holla 27e83f7dd9 genirq: Delay incrementing interrupt count if it's disabled/pending ... commit a946e8c717f9355d1abd5408ed0adc0002d1aed1 upstream. In case of a wakeup interrupt, irq_pm_check_wakeup disables the interrupt and marks it pending and suspended, disables it and notifies the pm core about the wake event. The interrupt gets handled later once the system is resumed. However the irq stats is updated twice: once when it's disabled waiting for the system to resume and later when it's handled, resulting in wrong counting of the wakeup interrupt when waking up the system. This patch updates the interrupt count so that it's updated only when the interrupt gets handled. It's already handled correctly in handle_edge_irq and handle_edge_eoi_irq.
