[PATCH 12/13] iio: light: Remove redundant dev_err()/dev_err_probe()
From: Pan Chuang
Date: Fri Jul 17 2026 - 05:55:45 EST
Since commit 55b48e23f5c4 ("genirq/devres: Add error handling in
devm_request_*_irq()"), devm_request_irq() and devm_request_threaded_irq()
automatically log detailed error messages on failure. Remove the
now-redundant driver-specific dev_err() and dev_err_probe() calls.
