TTY: use appropriate printk priority level
Mandeep Singh Baines [Sun, 6 Feb 2011 17:31:53 +0000 (09:31 -0800)]
printk()s without a priority level default to KERN_WARNING. To reduce
noise at KERN_WARNING, this patch set the priority level appriopriately
for unleveled printks()s. This should be useful to folks that look at
dmesg warnings closely.
