They all add the name of the affected device manually to the log message. This can be simplified by using the dev_*() variants of printk, which include the device information and make a separate call to dev_name() unnecessary. The KMSG_COMPONENT and the pr_fmt() definition can be dropped. Note that this removes the "dasd: " prefix from the one pr_info() call in dasd_init(). However, the log message already provides all relevant information.
