From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
Subject: lib/math: avoid trailing newline hidden in pr_fmt()
pr_xxx() functions usually have a newline at the end of the logging
message.
Here, this newline is added via the 'pr_fmt' macro.
In order to be more consistent with other files, use a more standard
convention and put these newlines 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.
