To: Michal Januszewski; +Cc: Bartlomiej Zolnierkiewicz, linux-fbdev, linux-kernel
Linus recently broke the printk without KERN_CONT behavior.
Fix it for uvesafb.
While there, convert printk(KERN_<LEVEL> to pr_<level>.
Add pr_fmt and remove the embedded prefixes.
Miscellanea:
o Coalesce formats and realign arguments
o Add a missing space to a format when coalescing.
