Since devm_request_irq() is a static inline wrapper around devm_request_threaded_irq(), it also benefits from this automatic logging. Remove the now-redundant dev_err() and dev_err_probe() calls in usb drivers that follow these devm_request_*_irq() functions, as the core now provides more detailed diagnostic information on failure.
