[PATCH] EDAC: Remove redundant dev_err()

[PATCH] EDAC: Remove redundant dev_err()

[Pan Chuang]

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() calls.
