Subject: Add PR_PREFIX to pr_xyz() macros
From: Martin Schwidefsky <schwidefsky@xxxxxxxxxx>
A common reason for device drivers to implement their own printk macros is
the lack of a printk prefix with the standard pr_xyz macros. Introduce a
pr_fmt macro that is applied for every pr_xyz macro to the format string.
The most common use of the pr_fmt macro would be to add the name of the
device driver to all pr_xyz messages in a source file.
