Subject: [PATCH 0/3] media: cec: Remove redundant error messages on IRQ request failure
Date: Thu, 23 Jul 2026 17:54:56 +0800 [thread overview]
Message-ID: <20260723095500.523448-1-panchuang@vivo.com> (raw)
devm_request_threaded_irq() and devm_request_any_context_irq()
automatically log detailed error messages on failure via
the devm_request_result() helper, which prints device
name, IRQ number, handler functions, and error code.
Since devm_request_irq() is a static inline wrapper around
devm_request_threaded_irq(), it also benefits from this
automatic logging.
Remove the now-redundant dev_err() and dev_err_probe() calls
in cec drivers that follow these devm_request_*_irq()
functions, as the core now provides more detailed diagnostic
information on failure.
