Rajeev Kumar 99805a7ac3 qcacld-3.0: Fix race condition between PM suspend and fw irq ... PM suspend and FW interrupt handler is running at same time which is leading to multiple race conditions and host is missing FW wake up interrupt which is causing APPS not waking up reliably. Define .suspend_noirq and .resume_noirq callbacks and make sure there is no pending FW interrupt before allowing PM suspend to complete. Kernel PM suspend framework gives guarantee that suspend_noirq and device interrupt handler can't run simultaneously. This helps WLAN driver to reliably detect FW wake up interrupt during PM suspend and fail PM suspend gracefully if FW has requested for initial wake up.
