That leaves a\nwindow where cs35l33_irq_thread() can still run after suspend has closed\noff live register access.\n\nA running system can reach this during runtime PM while the driver still\nhas critical fault IRQs unmasked. If the threaded handler runs in that\nwindow, it reads volatile INT_STATUS_1/2 after cache_only has been\nenabled, ignores the regmap_read() failures, and can still drive the\nAMP_SHORT_RLS, CAL_ERR_RLS, OTE_RLS, and OTW_RLS release paths.\n\nUse disable_irq() before entering cache_only/power-off so any in-flight\nthreaded handler is drained and no new IRQ thread can run during the\nsuspended state. Re-enable the IRQ only after runtime_resume() has\nrestored live register access with regcache_sync(). Since probe only\nwarns if devm_request_threaded_irq() fails, track whether the IRQ was\nactually installed before disabling or re-enabling it."
