Subject: [PATCH v2] kconfig: Deletion of unnecessary checks before the function
 call "sym_calc_value"

From: Markus Elfring <elfring@...rs.sourceforge.net>

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.
