[PATCH] uvesafb: Fix continuation printks without KERN_LEVEL to pr_cont, neatening

From: Joe Perches
Date: Mon Jun 12 2017 - 13:06:01 EST

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.
