Subject: [PATCH][4/5] floppy.c: Add explicit/better printk() levels
There are lots of printk() statements in floppy.c - more or less all of
them without explicit message levels.
Since a lot of these levels (IMHO) are not warnings, but of a more
informational nature, this patch adds explicit levels to most of the
printk()'s and modifies some of them to not be KERN_WARNING.
