Subject: [PATCH 4/5] ide-floppy: convert driver to the new debugging macro
Also:
- leave in the possibility for optimizing away all debugging macros
- add a PFX macro and prepend all printk calls with it for consistency
- change idefloppy_create_rw_cmd's 1st arg from idefloppy_floppy_t * to
ide_drive_t *.
- add a missing printk-level in idefloppy_init
- fix minor checkpatch warnings
