From: Yangtao Li tiny.windzz@gmail.com
commit 12cd53aff5ea0359b1dac91fcd9ddc7b9e646588 upstream.
Prefix all printk/pr_<level> messages with "random: " to make the logging a bit more consistent.
Miscellanea:
o Convert a printks to pr_notice o Whitespace to align to open parentheses o Remove embedded "random: " from pr_* as pr_fmt adds it
