Subject: [PATCH] staging: pi433: remove unnecessary new line escape sequence
 characters
Message-ID: <YfYtsiKbOXghIN+5@mail.google.com>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Precedence: bulk

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.
