Subject: [PATCH] staging: pi433: remove unnecessary new line escape sequence
characters
In this driver there were occurences of '\n'-ended strings when using
dev_dbg function which isn't required which most likely were leftovers
from a previous printk/pr_<level> implementation.
This patch removes the extraneous '\n' characters to make it consistent
with the other dev_dbg instances.
