Subject: [PATCH] floppy: Neaten message logging
Use a more current style to prefix "floppy: " on
all messages.
Convert DPRINT to emit at KERN_DEBUG.
Other miscellaneous logging changes:
o Add missing newline
o Remove embedded "floppy" style prefixes
o Remove trailing periods to standardize style
o Consolidate two logging lines into one
o Convert args... to ... and ##__VA_ARGS__

This could also probably use a pr_fmt so that
all the messages are prefixed.
