Subject: [PATCH] iio: adc: ad4062: Replace IRQF_ONESHOT with IRQF_NO_THREAD
Date: Mon, 23 Feb 2026 14:45:13 +0800 [thread overview]
Message-ID: <20260223-ad4062-v1-1-8ee93ea173a6@gmail.com> (raw)
In ad4062_request_irq(), when request irq for "gp1", the code uses
IRQF_ONESHOT flag, which is not appropriate for a primary handler
that does not have a secondary threaded handler.
And since commit aef30c8d569c ("genirq: Warn about using IRQF_ONESHOT
without a threaded handler"), the IRQ core checks IRQF_ONESHOT flag
in IRQ request and gives a warning if there is no threaded handler.
Since there is no threaded handler, replace devm_request_threaded_irq
with devm_request_irq, and replace IRQF_ONESHOT with IRQF_NO_THREAD.
Also remove an extraneous semicolon at the end of
ad4062_write_raw_dispatch().
Found by code review, compile pass.
Fixes: d5284402d28f ("iio: adc: Add support for ad4062")
