Subject: [PATCH][1/5] floppy.c: Initial (partial) CodingStyle cleanup
This is a basic CodingStyle cleanup for drivers/block/floppy.c
There are no functional changes in this patch.
Changes made are :
- remove some blank lines and insers others where it improves readability
- make comments a bit more similar in style
- make most lines fit within 80 columns
- remove some unneeded curly braces
- remove some trailing newlines
- add some missing spaces
- other minor trivialities
The reason for starting with this patch is simply to make the file nicer
to work with for me and get whitespace changes and such out of the way
from the beginning (and of course also to make it conform better to the
CodingStyle document).
