The variable len is not being inintialized and the uninitialized value is being returned. However, this return path is never reached because the default case in the switch statement returns -ENOSYS. Clean up the code by replacing the return -ENOSYS with a break for the default case and returning -ENOSYS at the end of the function. This allows len to be removed. Also remove redundant break that follows a return statement.
