[PATCH 5/9] staging: ks7010: refactor, change retval to ret

[Tobin C. Harding]

Code can be refactored to take advantage of indentation removal in
previous commit. Code is still nested quite deeply. Variable name
retval takes up six characters, this is significant because 80
character line limit is being hit frequently.

Change variable name retval to ret to get an extra three characters to
fit on each line.
