[PATCH 1/3] staging: ks7010: invert conditional, reduce indentation

["Tobin C. Harding" <me@xxxxxxxx>]

Code is unnecessarily nested. Function body is guarded by an if
statement, we can invert the if statement conditional and return,
subsequent code can have the indentation reduced.

Invert conditional, change '&&' to '||' , '>' to '<=' and '!=' to
'=='. Return if new conditional evaluates to true. Reduce indentation
in subsequent code.
