Subject: [PATCH 2/5] serial: imx: Remove redundant dev_err()
Date: Wed, 22 Jul 2026 11:43:30 +0800	[thread overview]
Message-ID: <20260722034342.316755-3-panchuang@vivo.com> (raw)
In-Reply-To: <20260722034342.316755-1-panchuang@vivo.com>

Since commit 55b48e23f5c4 ("genirq/devres: Add error handling in
devm_request_*_irq()"), devm_request_irq() automatically logs
detailed error messages on failure. Remove the now-redundant
driver-specific dev_err() calls.
