printk() is the raw way to print output and should be avoided. For drivers with defined "struct device object", dev_*macro() is prefer to standardize the output format within the subsystem.
If no "struct device object" is defined prefer pr_*macro() over printk(). This patch Replace printk having a log level with the appropriate output format according to the order of preference. Change string explicitly mentioning function name to "%s...", __func__.
