printk() is the raw way to print output and should be avoided. For drivers with defined "struct device object", dev_*macro() is prefer and for "struct netdevice object", netdev_*macro() is prefer over dev_*macro() 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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
