Input: aiptek - remove redundant assignment to variable ret

Variable ret is being assigned a value that is never read, it is
being re-assigned again in either path of the if statement. The
assignment is redundant and can be removed.

Cleans up clang scan build warning:
Although the value stored to 'ret' is used in the enclosing expression,
the value is never actually read from 'ret' [deadcode.DeadStores]
