Subject: Security: Check if either 'main' or 'setting' is NULL.
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=b2a0469394af080573e168b4f750263e3959e7e5;p=fll

Security: Check if either 'main' or 'setting' is NULL.

Name the void pointer 'setting' as 'void_setting' for consistency purposes.
Note that this should not be named 'void_setting' in the header files.
