Subject: [PATCH v3] kconfig: Delete unnecessary checks before the function
 call "sym_calc_value"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 7 Jul 2015 21:48:23 +0200

The sym_calc_value() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
