From d9bb189e25f14578ca74d6a3aa9f9a467f6f6595 Mon Sep 17 00:00:00 2001 From: Stefan Kerkmann Date: Thu, 7 Jul 2022 09:27:50 +0200 Subject: [Core] Update mpaland/printf to eyalroz/printf fork (#16163) mpaland printf implementation was abandoned in ~2019 and the fork by eyalroz is now regarded to be the goto replacement of it. So this commit incoporates the changes needed to use this fork in QMK.
