Checking common/cmd_ini.c: CONFIG_INI_MAX_NAME... Checking common/cmd_ini.c: CONFIG_INI_MAX_SECTION...
And I don't see anything. I did this since manually inspecting things and the code looks correct here but I could see cppcheck failing to figure it out (and I could see the code being optimized, we pass line as a pointer but then also return that back..).

Same result with Cppcheck 1.67

To me it looks as if it complained due to possibly incorrect CONFIG_INI_MAX_LINE settings?

Could be, but that'd be a compile-time failure if it's defined but not to a numerical value.
