SubjectPATCH][1/2] ide-tape: small cleanups - cosmetic; unneeded return parentheses and needles spaces in function declarations

The patch removes a bunch of unnessesary parantheses from return
statements. There are tons of return statements that look like this:
return (-EIO); return (fn()); etc.
The patch removes these unneeded parentheses.
The patch also removes a lot of spaces from function declarations. There
is some inconsistency in the file, some functions are declared as
void fn() { }
and some as
void fn () { }
So, the patch changes them to all use a common style. I picked the
void fn() { }
form, since (a) it seems to be the most common form used in the kernel as
a whole, (b) it is the form used in Documentation/CodingStyle, and (c) it
is the form that reduces the filesize a bit :)
