pr_xxx() functions usually have '\n' at the end of the logging message.
Here, this '\n' is added via the 'pr_fmt' macro.
In order to be more consistent with other files, use a more standard
convention and put these '\n' back in the messages themselves and remove it
from the pr_fmt macro.
While at it, use __func__ instead of hardcoding a function name in the
last message.
