Message-Id: <1244802742-14107-1-git-send-email-vapier@gentoo.org>

Subject: [PATCH] tty: bfin_jtag_comm: clean up printk usage
The original patch garned some feedback and a v2 was posted, but that
version seems to have been missed when merging the driver.
At any rate, this cleans up the printk usage as suggested by Jiri Slaby.
