Subject: [PATCH 00/26] dmaengine: Remove redundant error messages on IRQ request failure
Date: Thu, 9 Jul 2026 21:58:04 +0800 [thread overview]
Message-ID: <20260709135846.97972-1-panchuang@vivo.com> (raw)
Commit 55b48e23f5c4b6f5ca9b7ab09599b17dcf501c10 ("genirq/devres: Add
error handling in devm_request_*_irq()") added automatic error logging
to devm_request_threaded_irq() and devm_request_any_context_irq() via
the new devm_request_result() helper. The helper prints device name,
IRQ number, handler functions, and error code on failure.
Since devm_request_irq() is a static inline wrapper around
devm_request_threaded_irq(), it also benefits from this automatic
logging.
This series removes the now-redundant dev_err() and dev_err_probe() calls
in dmaengine drivers that follow these devm_request_*_irq() functions,
as the core now provides more detailed diagnostic information on failure.
