From 158ea2d2b2ff8fb49f39209a31b4920f13193a3d Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Sun, 14 Nov 2021 20:48:44 -0600 Subject: kbuild: Fix -Wimplicit-fallthrough=5 error for GCC 5.x and 6.x -Wimplicit-fallthrough=5 was under cc-option because it was only available in GCC 7.x and newer so the build is now broken for GCC 5.x and 6.x: gcc: error: unrecognized command line option '-Wimplicit-fallthrough=5'; did you mean '-Wno-fallthrough'? Fix this by moving -Wimplicit-fallthrough=5 under cc-option.
