Build error in latest master

[buelowp]

Later versions of GCC have started to generate the warning

main.cpp:1493:43: error: ‘%s’ directive output may be truncated writing up to 557 bytes into a region of size 5 [-Werror=format-truncation=]
 1493 |         snprintf(buffer, sizeof(buffer), "%s", chip);
      |                                           ^~

and because -Wall and -Werror are used, this causes the build to fail. I've attached the patch I used, but there may be a better solution.
