[PATCH] mmc: host: Remove redundant dev_err()/dev_err_probe()

Newsgroups org.kernel.vger.linux-omap,org.infradead.lists.linux-amlogic,org.infradead.lists.linux-arm-kernel,org.kernel.vger.linux-arm-msm,org.kernel.vger.linux-kernel,org.kernel.vger.linux-mmc
Message-ID <[email protected]>
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.
