ASoC: rt5640: Fix sleep in atomic context
Following prints are observed while testing audio on Jetson AGX Orin which has onboard RT5640 audio codec: BUG: sleeping function called from invalid context at kernel/workqueue.c:3027 in_atomic(): 1, irqs_disabled(): 128, non_block: 0, pid: 0, name: swapper/0 preempt_count: 10001, expected: 0 RCU nest depth: 0, expected: 0 ------------[ cut here ]------------ WARNING: CPU: 0 PID: 0 at kernel/irq/handle.c:159 __handle_irq_event_percpu+0x1e0/0x270 ---[ end trace ad1c64905aac14a6 ]- The IRQ handler rt5640_irq() runs in interrupt context and can sleep during cancel_delayed_work_sync(). The only thing which rt5640_irq() does is cancel + (re-)queue the jack_work delayed_work. This can be done in a single non sleeping call by replacing queue_delayed_work() with mod_delayed_work(), avoiding the sleep in atomic context.
