[PATCH v3 4/6] iio: light: ltr501: Power down chip if request irq fails
From: Esben Haabendal
Date: Tue Aug 04 2026 - 13:11:25 EST
In case devm_request_threaded_irq() failed, we were leaving the chip
powered instead of powering it down again. Power down the chip switching
ALS and PS modes to standby.
The dev_err() message was causing duplicated error messages, as
devm_request_threaded_irq() calls dev_err_probe() on failure.
Fixes: 7ac702b3144b ("iio: ltr501: Add interrupt support")
