Subject: [PATCH] mmc: host: Remove redundant dev_err()/dev_err_probe()
Date: Fri, 17 Jul 2026 18:14:49 +0800	[thread overview]
Message-ID: <20260717101508.635969-1-panchuang@vivo.com> (raw)

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.
