Subject: ASoC: rt5640: Fix sleep in atomic context
From: Sameer Pujar <spujar@xxxxxxxxxx>
commit 70a6404ff610aa4889d98977da131c37f9ff9d1f upstream.
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().
Fix this by running IRQ handler, rt5640_irq(), in thread context.
Hence replace request_irq() calls with devm_request_threaded_irq().
