I sent it out too soon...
Other advantages:
- The pr_*() calls use pr_fmt(), so you can set default prefixes (like
__FILE__, __function, __LINE) at one place at the top of your driver source
file.
- pr_debug() is automatically left out if DEBUG is not defined (unless
CONFIG_DYNAMIC_PRINTK_DEBUG is set).
